'''Idar-Oberstein''' ({{IPA|de|ˌiːdaːɐ̯ ˈʔoːbɐˌʃtaɪn|lang|De-Idar-Oberstein.ogg}}) is a town in the [[Birkenfeld (district)|Birkenfeld]] [[Districts of Germany|district]] in [[Rhineland-Palatinate]], Germany. As a ''Große kreisangehörige Stadt'' (large city belonging to a district), it assumes some of the responsibilities that for smaller municipalities in the district are assumed by the district administration. Today's town of Idar-Oberstein is the product of two rounds of administrative reform, one in 1933 and the other in 1969, which saw many municipalities amalgamated into one. The various ''[[Ortsteil|Stadtteile]]'' have, however, retained their original identities, which, aside from the somewhat more urban character encountered in Idar and Oberstein, tend to hark back to each centre's history as a rural village. Idar-Oberstein is known as a gemstone town, and also as a [[garrison]] town. It is also the largest town in the [[Hunsrück]].

==Geography==
The town lies on the southern edge of the [[Hunsrück]] on both sides of the river [[Nahe (Rhine)|Nahe]].

===Climate===
Yearly [[precipitation]] in Idar-Oberstein amounts to 774&nbsp;mm, falling into the middle third of the precipitation chart for all Germany. At 57% of the [[German Weather Service]]'s [[weather station]]s, lower figures are recorded. The driest month is April. The most rainfall comes in December. In that month, precipitation is 1.6 times what it is in April. Precipitation hardly varies at all and is evenly spread throughout the year. At only 13% of the weather stations are lower seasonal [[:File:IDAR OBERSTEIN nieder.svg|swings]] recorded.

The territorial history of Idar-Oberstein's individual centres is marked by a considerable splintering of lordly domains in the local area. Only in [[Napoleon]]ic times, beginning in 1794, with its reorganization and merging of various territorial units, was some order brought to the traditional mishmash of local lordships. However, shortly thereafter, the [[Congress of Vienna]] brought the future town division once again, as the river Nahe became a border, and the centres on its north bank were thereby grouped into the Principality of Birkenfeld, an [[exclave]] of the [[Duchy of Oldenburg|Grand Duchy of Oldenburg]], most of whose territory was in what is now northwest Germany, with a coastline on the [[North Sea]].

The towns of Idar and Oberstein belonged to the [[Barons of Daun-Oberstein]] (who later became the [[Counts of Falkenstein (Rhineland-Palatinate)|Counts of Falkenstein]]) until 1670. In 1865, both Idar and Oberstein were granted town rights, and finally in 1933, they were forcibly united (along with the municipalities of Algenrodt and Tiefenstein) by the [[Nazi Party|Nazis]] to form the modern town of Idar-Oberstein.

===History up to French reorganization beginning in 1794===
The constituent community of Oberstein grew out of the [[Imperially immediate]] Lordship of Oberstein. The ''Herren vom Stein'' (“Lords of the Stone”) had their first documentary mention in 1075. Their seat was at Castle Bosselstein, now known as the ''Altes Schloss'' (“Old Palatial Castle”), above the cliff where the ''Felsenkirche'' (“Rock Church”) - itself mentioned as early as the 12th century - would later be built. The core of the area over which the lordship held sway was framed by the rivers Nahe, Idarbach, Göttenbach and Ringelbach. After 1323, the Lords of the Stone styled themselves “von Daun-Oberstein”, and managed to considerably expand their domain even into lands south of the Nahe and into the Idarbann. As the lordly seat with its castle and fortifications – remnants of the old town wall built about 1410 can still be seen – Oberstein developed the characteristics of a town, however without ever earning the legal status of a market town (''Flecken''). In 1682, the [[Counts of Leiningen]]-Heidesheim, and in 1766 the [[Limburg Stirum|Counts of Limburg-Styrum]], became the owners of the Lordship of Oberstein, which largely shrank back to the above-mentioned lordly core after the Idarbann was [[ceded]] to the “Hinder” [[County of Sponheim]] in 1771. In 1776, the [[Margrave]]s of [[Baden]] became the owners of the Lordship after the “Hinder” County of Sponheim was partitioned.

It is known from [[archaeological]] finds that human settlement in what is now Idar goes back to the very earliest times. The constituent community of Idar on the Nahe's right bank belonged, as did the villages of Enzweiler, Algenrodt, [[Mackenrodt]], [[Hettenrodt]], Hettstein, Obertiefenbach and [[Kirschweiler]], to the Idarbann. This area belonged mostly to the Lords of Oberstein, and it therefore shares a history with Oberstein; however, in some centres, notably Tiefenbach and Kirschweiler, some estates and rights were held by other lords, such as the [[Waldgrave]]s and Rhinegraves and [[Tholey Abbey]].

The constituent community of Tiefenstein arose from the merger of the villages of Tiefenbach and Hettstein in 1909. This Idarbann community's territorial history is the same as Idar's and Oberstein's. Tiefenbach was mentioned as an estate in a 1283 document; a further documentary mention from 1051 cannot be related to the village with any certainty. Hettstein was mentioned as ''Henzestein'' or ''Hezerten'' in 1321 and had among its inhabitants Waldgravial subjects.

The village of Algenrodt had its first certain documentary mention as ''Alekenrod'' in a 1321 Oberstein enfeoffment document. In 1324, the Lords of Oberstein pledged it to the Waldgraves and Rhinegraves of Kyrburg. But for this, Algenrodt shares a history with the other Idarbann communities.

Enzweiler boasts traces of human habitation going back to [[Ancient Rome|Roman]] times. In 1276, Tholey Abbey owned a mill near Enzweiler. The village itself might have arisen in the 14th century, and it was always part of the Idarbann.

The village of Georg-Weierbach north of the Nahe, built in a way resembling terraces on land that falls steeply towards the river, likely goes back to the foundation of a church by [[Archbishopric of Mainz|Archbishop of Mainz]] [[Hatto II]] in the 10th century. In the 11th century, the village was mentioned in connection with the Lords of Wirebach (that is, Weierbach). In 1327, the village, which was for a short time held by the Lords of Randeck, was largely sold off to the Waldgraves and Rhinegraves and grouped into the ''[[Amt (country subdivision)|Amt]]'' of Kyrburg. The form “Georg-Weierbach” stems from the [[Saint George|church's patron saint]].

Göttschied, which had its first documentary mention in 1271, belonged together with Regulshausen, [[Gerach, Rhineland-Palatinate|Gerach]] and [[Hintertiefenbach]] to Mettlach Abbey. These four villages were therefore known as the ''Abteidörfer'' (“abbey villages”), and in 1561, they were sold to the “Hinder” County of Sponheim.

Hamerzwiller (nowadays called Hammerstein) was mentioned in 1438 in a taxation book kept by the County of Sponheim, and had been held by the “Hinder” County of Sponheim as early as 1269, when that county enfeoffed the Counts of Schwarzenberg with it.

Regarded as the origin of the village of Kirchenbollenbach is the foundation of a church by Archbishop of Mainz [[Willigis]] sometime after 975. The earliest documentary evidence of the village goes back to 1128 when it was called ''Bolinbach''. It is first known to have been a [[fief]] held by the Lords of Schwarzenberg from the Counts of Zweibrücken, whereafter it passed in 1595 to the Waldgraves and Rhinegraves of Kirn. One local peculiarity here was that a [[Catholic]] sideline of the otherwise mainly [[Protestant]] Rhinegraves ended up holding sway in Kirchenbollenbach, and under Prince Johann Dominik of [[Principality of Salm|Salm]]-Kyrburg, this line not only founded a new Catholic parish but also introduced a [[simultaneum]] at the local church.

The foundation stone of today's village of Mittelbollenbach is said to be the estate of Bollenbach, which was mentioned in 1283 as a holding of the Lords of Oberstein in the area of the Winterhauch woodland. In 1432, the [[Lorraine (duchy)|Dukes of Lorraine]] were enfeoffed with Nahbollenbach and Mittelbollenbach, which in the wake of the death of the last Lord of Oberstein led to bitter arguments over the complicated inheritance arrangements. Only in 1778 did Lorraine finally relinquish its claims in [[Electoral Trier]]'s favour.

Until 1667, Nahbollenbach and Mittelbollenbach shared the same history. Then, Nahbollenbach was acknowledged by Lorraine as an [[allodial]] holding of Oberstein, although beginning in 1682 it was an Electoral-Trier fief held by Oberstein.

The “abbey village” of Regulshausen belonged to Mettlach Abbey, who sold it in 1561 to the “Hinder” County of Sponheim. The oldest documentary mention comes from 1491.

The village of Weierbach – not to be confused with Georg-Weierbach mentioned above – had its first documentary mention in 1232 as ''Weygherbach'', and belonged to the ''Amt'' of Naumburg in the “Further” County of Sponheim, which itself was later held by the Margraves of Baden, which gave the village its onetime alternative name, Baden-Weierbach. The oft-used other alternative name, Martin-Weierbach, stems from the [[Martin of Tours|church's patron saint]].

===French, Oldenburg and Prussian times===
After the [[France|French]] dissolved all the old lordships, they introduced a sweeping reorganization of territorial (and social) structure beginning in 1794. The whole area belonged to the [[Arrondissements of France|arrondissement]] of Birkenfeld in the [[Departments of France|Department]] of [[Sarre (department)|Sarre]]. Until 1814, this was French territory. The introduction of the [[Napoleonic Code|''Code civil des Français'']], justice reform and, foremost, the abolition of the noble and clerical classes with the attendant end to compulsory labour and other duties formerly owed the now powerless lords quickly made French rule popular. However, there was quite a heavy tax burden imposed by the new rulers, and there was also continuing [[conscription]] of men into the French army. Both of these things weighed heavily on France's [[Rhineland]] citizens.

After [[Napoleon]]ic rule ended, the area was restructured. On the grounds of Article 25<ref>Acte du Congrès de Vienne du 9 juin 1815, Art. 25: ''Possessions prussiennes sur la rive gauche du Rhin''</ref> of the concluding acts of the [[Congress of Vienna]], the northern part of the Department of Sarre was at first given to the Kingdom of [[Prussia]] in June 1815.

Since Prussia was obliged under the terms of the 1815 [[Treaty of Paris (1815)|Treaty of Paris]] to cede an area out of this parcel containing 69,000 inhabitants to other powers – 20,000 souls each to [[Saxe-Coburg and Gotha]] and the [[Duchy of Oldenburg|Duke of Oldenburg]], along with smaller cessions to smaller princes – and since this had also been reconfirmed in Article 49<ref>Acte du Congrès de Vienne du 9 juin 1815, Art. 49: ''Territoires réservés pour les maisons d’Oldenbourg, de Saxe-Cobourg, de Mecklenbourg-Strelitz, et le comte de Pappenheim''</ref> of the concluding acts of the Congress of Vienna, the region underwent further territorial division.

The villages south of the Nahe – Hammerstein, Kirchenbollenbach, Mittelbollenbach, Nahbollenbach and Martin-Weierbach – were therefore transferred in 1816 to the Principality of Lichtenberg, held by the Dukes of Saxe-Coburg and Gotha. The Dukes were not satisfied with this territorial gain, and for their part, the people in the territory were not satisfied with their new rulers. In 1834, the area was sold for two million ''[[Thaler]]'' to Prussia and made into the Sankt Wendel district. Later, after the [[First World War]], the [[Treaty of Versailles]] stipulated, among other things, that 26 of the Sankt Wendel district's 94 municipalities had to be ceded to the [[United Kingdom|British]]- and French-[[Military occupation|occupied]] [[Saar (League of Nations)|Saar]]. The remaining 68 municipalities then bore the designation “Restkreis St. Wendel-Baumholder”, with the first syllable of ''Restkreis'' having the same meaning as in English, in the sense of “left over”. The Prussians were themselves not well liked leaders, as they sometimes imposed their order with military might. They were known, and hated, for, among other things, putting a protest rally of the [[Hambach Festival]] in [[Sankt Wendel]] in May 1832, complete with a [[liberty pole]] in the Napoleonic tradition, to an end using military force, after Coburg had called on Prussia for help in the matter.

Idar, Oberstein, Tiefenstein, Algenrodt, Enzweiler, Georg-Weierbach, Göttschied, Enzweiler and Regulshausen became on 16 April 1817 part of the newly created Principality of Birkenfeld. They also became the ''Amt'' of Oberstein, which comprised the ''Bürgermeistereien'' (“Mayoralties”) of Herrstein, Oberstein and Fischbach. French law was allowed to stand. The Duke did, however, issue a ''Staatsgrundgesetz'' (“Basic State Law”) with which the people were not in agreement, because they would rather have stayed with Prussia. This continued work on the patchwork quilt of [[Microstate|little states]] covering Germany was judged very critically in Idar and Oberstein, whereas [[Birkenfeld]], which had as a result of the new political arrangement been raised to residence town, found little to complain about. The jewellery industry there, which even by this time had become national, perhaps international in scope, and indeed the jewel dealers themselves, who now found themselves living in a little provincially oriented town, perceived the new arrangement, though, as a backward step, particularly so after the years that France had ruled. It had had its worldly metropolis of [[Paris]] with its good business. The dealers, therefore, tried energetically, but without success, to have their land reannexed to Prussia. On the other hand, the Oldenburgers quickly managed to make themselves popular among the people by installing an unselfish government that established an independent judiciary and introducing various programmes that favoured farmers and the economy. A well regulated [[school system]] – in 1830, a public school was built in Oberstein – and the temporary suspension of military conscription only helped to support this positive picture. Roads were expanded and a postal coach service (for persons, bulk mailings and bulky goods) was set up. A further economic upswing was brought by the building of the [[Nahe Valley Railway]], especially when the stretch from [[Bad Kreuznach]] to Oberstein opened on 15 December 1859.

===Since the First World War===
When the [[First World War]] ended, Grand Duke Friedrich August of Oldenburg [[abdicated]], whereupon the ''Landesteil'' (literally “country part”) of Birkenfeld in the Free State of Oldenburg arose from the old principality. This ''Landesteil'', along with the whole Rhineland, was occupied by the French on 4 December 1918. They did not withdraw until 30 June 1930.

At the Oldenburg ''[[Landtag]]'' elections in 1931, the [[NSDAP]] received more than 37% of the votes cast, but could not form the government. After the Nazis had first given up a declaration of tolerance for the existing government, they were then soon demanding that the ''Landtag'' be dissolved. Since this was not forthcoming, the Nazis filed suit for a referendum, and they got their way. This resulted in [[Dissolution of parliament|dissolution]] on 17 April 1932. In the ensuing new elections on 20 May, the Nazis won 48.38% of the popular vote, and thereby took 24 of the 46 seats in the ''Landtag'', which gave them an absolute majority. In Idar, which was then still a self-governing town, the National Socialists received more than 70% of the votes cast. They could thereby already govern, at least in Oldenburg, with endorsement by the [[German National People's Party]], which had two seats at its disposal, even before [[Adolf Hitler]]’s [[Machtergreifung|official seizure of power]] in 1933. One of the new government’s first initiatives was administrative reform for Oldenburg, which was followed on 27 April 1933 by the similar ''Gesetz zur Vereinfachung und Verbilligung der Verwaltung'' (“Law for simplifying administration and reducing its cost”) for the ''Landesteil'' of Birkenfeld. Through this new law, 18 formerly self-administering municipalities were amalgamated; this included the self-administering towns (having been granted town rights in 1865) of Idar and Oberstein, which were amalgamated with each other and also with the municipalities of Algenrodt and Tiefenstein to form the new town of Idar-Oberstein. The law foreshadowed what was to come: It would be applied within a few weeks, without further discussion or participation, to the exclusion of the public and against the will of municipalities, who had not even been asked whether they wanted it, to places such as Herrstein and Oberwörresbach, Rötsweiler and Nockenthal, or Hoppstädten and Weiersbach. The restructuring also afforded the Nazis an opportunity to get rid of some “undesirables”; under ''Kreisleiter'' (district leader) Wild from Idar, all significant public positions were held until Hitler's downfall by Nazis.

In 1937, on the basis of the [[Greater Hamburg Act]], the ''Landesteil'' of Birkenfeld was dissolved and transferred together with the “Restkreis St. Wendel-Baumholder” to the Prussian district of Birkenfeld,<ref>Gesetz über Groß-Hamburg und andere Gebietsbereinigungen vom 26. Januar 1937, Artikel&nbsp;II, §&nbsp;8&nbsp;(1)</ref> a deed which put all of what are today Idar-Oberstein's constituent communities in the same district.

After the [[Second World War]], along with the whole district, the town's whole municipal area passed to the then newly founded [[States of Germany|state]] of [[Rhineland-Palatinate]].

On 1 April 1960, the town of Idar-Oberstein was declared a ''Große kreisangehörige Stadt'' (large town belonging to a district) by the state government, after the town itself had applied for the status.<ref>[http://rlp.juris.de/rlp/gesamt/BadKreuznachGkStV_RP.htm Landesverordnung über die großen kreisangehörigen Städte Bad Kreuznach, Idar-Oberstein und Neuwied vom 29. März 1960]{{Dead link|date=January 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

===Amalgamations===
In the course of administrative restructuring in [[Rhineland-Palatinate]], nine surrounding municipalities were amalgamated with Idar-Oberstein. On 7 June 1969, the municipalities of Enzweiler, Göttschied, Hammerstein and Regulshausen were amalgamated, and on 7 November 1970 they were followed by Georg-Weierbach, Kirchenbollenbach, Mittelbollenbach, Nahbollenbach and Weierbach.

Before the administrative restructuring, there were extensive, sometimes behind-closed-doors talks by the then mayor of Idar-Oberstein, Dr. Wittmann, with offers of negotiation to all together<!--NO, THAT IS NOT MISSPELT! “Altogether” has an altogether different meaning.--> 22 municipalities in the surrounding area. One of the reasons for this was a tendency that had been noted for people from Idar-Oberstein to move out of town to the surrounding municipalities, which were opening up extensive new building areas – among others Göttschied, [[Rötsweiler-Nockenthal]] and Kirschweiler – whereas within the town itself, given the problematic lie of the land, there were hardly any. The same problem saw to it that there was a dearth of land for industrial location. Surprising was the desire expressed by Weierbach, which came without one of Idar-Oberstein's initiatives, to join the new greater town, for at the time, Weierbach did not even border on the town, and Weierbach itself was then foreseen as the future nucleus of its own greater municipality, or perhaps even town, together with the municipalities of Fischbach, Georg-Weierbach and Bollenbach, which would have been amalgamated with this municipality had the original plan come about.

With the exception of Georg-Weierbach, the proposal to amalgamate these villages with the town of Idar-Oberstein had notable majorities, either in the villages themselves or on their councils, in favour of dissolving their respective municipalities and then merging with the town. Nevertheless, bitter discussions and even administrative legal disputes arose in the former ''Amt'' of Weierbach, which was now bereft of its core municipalities. In April 1970, the ''Amt'' of Weierbach lodged a constitutional grievance with the ''Verfassungsgerichtshof Rheinland-Pfalz'' (Rhineland-Palatinate Constitutional Court), which ruled on 8 July 1970 that the state law for administrative simplification in Rhineland-Palatinate was in parts unconstitutional. The right to self-administration of the ''Amt'' of Weierbach, it furthermore ruled, was being infringed, and the municipal league's vitality was being jeopardized. Thus, Weierbach, Georg-Weierbach, Nahbollenbach, Mittelbollenbach and Kirchenbollenbach were, with immediate effect, demerged from the town and reinstated as self-administering municipalities. After bitter arguments between the town of Idar-Oberstein together with the amalgamation supporters on the one side and the ''Amt'' of Weierbach together with the amalgamation opponents on the other, who promoted their views in [[demonstration (people)|demonstration]]s, at gatherings and in letter duels in [[newspaper]] correspondence pages, a poll was taken in early September 1970 with a vote in the ''Amt'' of Weierbach. The results favoured the state of affairs that had existed before the constitutional court's ruling with almost 80% of the vote in favour of amalgamation, whereas the remaining municipalities in the ''Amt'' of Weierbach, namely [[Sien, Germany|Sien]], [[Sienhachenbach]], [[Schmidthachenbach]], [[Fischbach, Birkenfeld|Fischbach]], Zaubach (a village that vanished in the late 20th century) and [[Dickesbach]], returned a vote of roughly 95% in favour of keeping the ''Amt'' of Weierbach.

With this expansion of the town, the centres of gravity in the Birkenfeld district had been shifted considerably. Idar-Oberstein could further grow as a [[Central place theory|middle centre]]: the educational facilities were expanded ([[Realschule]], Heinzenwies-[[Gymnasium (school)|Gymnasium]]), new building developments could be opened up (especially in Göttschied, Regulshausen and Weierbach), land was available for a new [[hospital]] building and there was room, too, for industrial and commercial operations to locate.

Since Idar-Oberstein had not only a good general infrastructure but also, after the Steinbach Reservoir was brought into service, a more than adequate water supply, the option of amalgamating themselves with the town became attractive to many further municipalities. On the initiative of Mayor Wittmann, who had a survey done by an [[Osnabrück]] planning bureau on the town's relationship with 25 other neighbouring municipalities, town council decided to promote the “unconditional amalgamation” of the municipalities of Fischbach, Dickesbach, Zaubach, [[Mittelreidenbach]], [[Oberreidenbach]], Schmidthachenbach, Sienhachenbach, Sien, Hintertiefenbach and [[Vollmersbach]]. The municipalities of Rötsweiler-Nockenthal, [[Siesbach]], Gerach, [[Veitsrodt]], Kirschweiler, Hettenrodt and [[Mackenrodt]] were each to receive an offer of amalgamation. The district administration in Birkenfeld then got involved, and it was decided by the district assembly (''Kreistag'') that Idar-Oberstein's amalgamation policy, which was deemed to be reckless<!-- For “rücksichtslos” – it might mean “indiscriminate”. -->, should be censured. Since a certain disenchantment with all these amalgamations had meanwhile set in both in the outlying centres and in the town of Idar-Oberstein itself, all further initiatives either got nowhere or were shelved.

===Schinderhannes===
Idar-Oberstein has its connections with the notorious outlaw Johannes Bückler (1777–1803), commonly known as [[Schinderhannes]]. His parents lived in Idar around 1790, and Oberstein was the scene of one of his earliest misdeeds in 1796. He spent a whole [[Louis d'or]] on drinks at an inn. He had stolen it from an innkeeper named Koch from Veitsrodt who had meant to use it to buy [[brandy]].<ref>Peter Bayerlein: Schinderhannes-Chronik, S. 45</ref>

Schinderhannes's sweetheart, Juliana Blasius (1781–1851), known as “Julchen”, came from Idar-Oberstein's outlying centre of Weierbach. She spent her childhood with her father and elder sister Margarethe as a [[Cantastoria|“bench singer”]] and a fiddler at markets and church fêtes. At [[Easter]] 1800, Schinderhannes saw “Julchen” for the first time at the Wickenhof<!--Yes, the name customarily took the article.-->, a now vanished [[Hamlet (place)|hamlet]] near [[Kirn]], where the 19-year-old danced. Their relationship yielded a daughter and a son, Franz Wilhelm. After Schinderhannes was beheaded for his crimes in 1803, Juliana married first a gendarme, with whom she had seven children, and then after his death a livestock herder and day labourer.<ref>[[Ernst Probst]]: ''Superfrauen 1 Geschichte''; Mainz-Kostheim 2001; S. 10</ref>

===The legend of the ''Felsenkirche'' (“Crag Church”)===
[[File:Felsenkirche (Idar-Oberstein) 2023.jpg|thumb|''Felsenkirche'' (“Crag Church”), a legendary church and symbol of the town]]
According to legend, there were two noble brothers, Wyrich and Emich, who both fell in love with a beautiful girl named Bertha. The brothers lived at Castle Bosselstein, which stood atop a 135&nbsp;m-high hill. Bertha was from a noble line that occupied the nearby Lichtenburg Castle.

Neither brother was aware of the other's feelings for Bertha. When Wyrich, the elder brother, was away on some unknown business, Emich succeeded in securing Bertha's affections and, subsequently, married her. When Emich announced the news to his brother, Wyrich's temper got the better of him. In the heat of the moment, he hurled his brother out of a window of the castle and sent him to his death on the rocks below.

Wyrich was almost immediately filled with remorse. With the counsel of a local abbot, he began a long period of penance. At this time, Bertha disappears from the historical record. Many romantics feel that she died of a [[broken heart]].

As Wyrich waited for a heavenly sign showing that he was forgiven, the abbot suggested that he build a church on the exact place where his brother died. Wyrich worked and prayed himself into exhaustion. However, the moment the church was completed, he received his sign: a miraculous [[spring (hydrology)|spring]] opened up in the church.

Wyrich died soon after this. When the local bishop came to consecrate the new church, he found the noble lord dead on its steps. Wyrich was later placed in the same tomb with his brother.

===Emigration and gemstones===
Idar-Oberstein is known as a gemstone centre. Until the 18th century, the area was a source for [[agate]] and [[jasper]]. A combination of low-cost labour and energy helped the gemstone-working industry flourish. The river Nahe provided free water power for the cutting and polishing machines at the mills.

In the 18th century, though, gemstone finds in the Hunsrück were dwindling, making life harder for the local people. Many left to try their luck abroad. Some went as far as [[Brazil]], where they found that gemstones could be recovered from open-pit mines or even found in rivers and streams. The locally common tradition of preparing meat over an open fire, [[churrasco]], was also adopted by the newcomers and even found its way back to their homeland by way of gemstone shipping. Agate nodules were shipped back as [[Sailing ballast|ballast]] on empty vessels that had offloaded cargo in Brazil. The cheap agates were then transported to Idar-Oberstein.

In the early 19th century, many people were driven out of the local area by hunger and also went to [[South America]]. In 1827, emigrants from Idar-Oberstein discovered the world's most important [[agate]] deposit in Brazil's state of [[Rio Grande do Sul]]. As early as 1834, the first delivery of agate from Rio Grande do Sul had been made to Idar-Oberstein. The Brazilian agate exhibited very even layers, much more even than those seen in the local agates. This made them especially good for making [[engraved gem]]s. Using locals’ technical knowledge of chemical dyes, the industry grew bigger than ever at the turn of the 20th century.

After the [[Second World War]], the region had to redefine itself once more, and it developed into a leading hub in the trade of gemstones from Brazil and [[Africa]]. That in turn provided local artists with a large selection of material and the region experienced a “third boom” as a gemstone centre. More recently, however, competition from [[Thailand]] and [[India]] has hit the region hard.{{citation needed|date=May 2013}}

===Coat of arms===
The German blazon reads: ''Im halbrunden silbernen Schild befindet sich ein aufgerichteter roter Forsthaken, begleitet im rechten Obereck von einer sechsblättrigen roten Rose mit goldenem Kelch und grünen Kelchblättern, links unten von einer roten Eichel.''

The town's [[Coat of arms|arms]] might in English [[heraldic]] language be described thus: Argent a cramp palewise sinister with a crossbar gules between in dexter chief a rose foiled of six of the second barbed and seeded proper and in sinister base an acorn slipped palewise of the second.

The [[charge (heraldry)|charge]]s are drawn from coats of arms formerly borne by both Idar and Oberstein before the two towns were merged in 1933. The current arms were approved by the Oldenburg Ministry of State for the Interior. The arms have been borne since 10 July 1934.<ref>[http://www.idar-oberstein.de/Das-Stadtwappen.143.0.html Description and explanation of Idar-Oberstein’s arms] {{webarchive|url=https://web.archive.org/web/20090523153814/http://www.idar-oberstein.de/Das-Stadtwappen.143.0.html |date=2009-05-23 }}</ref>

===Mediaeval buildings===
[[File:Felsenkirche Idar Oberstein.jpg|thumb|''Felsenkirche'' (“Crag Church”)]]
[[File:Idar-Oberstein Felsenkirche.jpg|thumb|Old Town with ''Felsenkirche'']]

====''Felsenkirche''====
The famous ''Felsenkirche'' (“Crag Church”) is the town's defining landmark. It came to be through efforts by Wirich IV of Daun-Oberstein (about 1415–1501), who in 1482 built the now Protestant church on the foundations of the ''Burg im Loch'' (“Castle in the Hole”).

As far as is now known, this [[castle]] was the first defensive position held by the Lords of Stein and a [[refuge castle]] for the dwellers of the village down below that was built into the great cave in the crag, the “Upper Stone” (or in [[German language|German]], ''Oberer Stein'') on the river Nahe. This, of course, explains the origin of the name “Oberstein”.

The “Castle in the Hole” was the only cave castle on the Upper Nahe. The ''Felsenkirche'' can nowadays be reached by visitors through a tunnel that was built in modern times.

====Castle Bosselstein====
[[File:Bosselstein.JPG|thumb|Castle Bosselstein]]
Up above the small church, on a knoll (''Bossel'') stands Castle Bosselstein, or rather what is left of it. The whole complex was forsaken in 1600, and all that stands now is a tower stump and remnants of the castle wall. In the Middle Ages, it was a stronghold to be reckoned with, with its two crescent moats and its two baileys.

Somewhat farther up, not far from Castle Bosselstein, the third castle arose about 1325, the one now known as Schloss Oberstein. Until 1624, it was the residence of the Counts of Daun-Oberstein. In 1855 it burnt down. In the years 1926 to 1956, the castle was used as a [[youth hostel]], and thereafter as an [[inn]].

In 1961, part of the east wall fell in. The castle club, ''Schloss Oberstein [[Eingetragener Verein|e.&nbsp;V.]]'', that was founded shortly thereafter, in 1963, has been worrying ever since about maintaining the acutely endangered building materials that make up this former four-tower complex. In 1998, the town of Idar-Oberstein became the castle's owner. Today there is once again a small inn, the Wyrich-Stube, and there are also now a few rooms restored by the castle club, which can be hired for festive occasions or cultural events.

===''St. Peter and Paul''===
''St. Peter und Paul'' is the Catholic {{not a typo|church}} in the constituent community of Idar. It was built in 1925 as a wooden church for the then town of Idar. Since the 17th century, the town's Catholics had had to make do with ecclesiastical services from Oberstein. By 1951, the church had fallen into such disrepair that it was extensively converted and expanded with stone.

===Theatre===
Besides the Town Theatre in the constituent community of Oberstein, there is also a [[cabaret]] stage. With Schloss Oberstein as the backdrop, the ''Theatersommer Schloss Oberstein'' (“Schloss Oberstein Theatre Summer”) is held each year.

===Museums===
[[File:Deutsches Edelsteinmuseum IO.JPG|thumb|Hauptstraße 118: The ''Deutsches Edelsteinmuseum'', housed in a representative Renaissance Revival villa (see under ''Buildings'' above)]]
Since the early 1960s [[tourism]] has grown in importance for Idar-Oberstein. Today it boasts a number of modern facilities such as the Steinkaulenberg, a gemstone mine open to visitors, and the German Gemstone Museum, as well as several recreational resorts. 
Nationally known is the ''Deutsches Edelsteinmuseum'' (German Gemstone Museum) in the constituent community of Idar, which boasts many gemstone exhibits.

The ''Museum Idar-Oberstein'' in the constituent community of Oberstein right below the famous ''Felsenkirche'' devotes itself to the specialized theme of “minerals”, and accordingly shows not only local places where gems were discovered, but also worldwide discovery places. The Idar-Oberstein jewellery industry and gemstone processing, too, and especially the [[agate]]-cutting operation, are presented in an impressive way.

Insights into the production of [[Art Deco]] jewellery as it was done about the turn of the 20th century are offered by the ''Industriemuseum Jakob Bengel'' in the constituent community of Oberstein. It is open the year round.

At the Steinkaulenberg gemstone mines, the only gemstone mine in [[Europe]] open to visitors, and at the ''Historische Weiherschleife'' – a gemstone-grinding mill – one can learn a few things about gemstone processing and Idar-Oberstein's history. [[Jasper]] is also featured there, for Idar-Oberstein is also an important centre for that semiprecious stone.

===Sport===
The town's best known sport club is [[SC 07 Idar-Oberstein]].

Idar-Oberstein has an indoor [[swimming pool]] and, since September 2005 an outdoor swimming pool fed by natural water. On the town's outskirts, a [[Friends of Nature]] house has been established, offering cyclists, hikers and tourists meals and lodging. Also, in nearby Kirschweiler is a [[golf course]].

The ''Schleiferweg'' (''Schleifer'' is German for “grinder” or “polisher”, a reference to the town's fame as a gem-processing centre; ''Weg'' simply means “way”) is a 22&nbsp;km-long signposted [[hiking]] trail round Idar. The path leads around the constituent communities of Idar, Oberstein, Göttschied, Algenrodt and Tiefenstein. Especially for sophisticated<!--same again--> hikers, the ''Schleiferweg'' offers a special hiking experience with a high section of path through thick forest. The trail leads by various tourist attractions, such as the ''Weiherschleife'', the Steinkaulenberg, the Kammerwoog (lake) or even the ''Wäschertskaulen'' spit roast house. With the good links to the town transport network, the trail can be broken up into as many shorter stretches as the hiker chooses.

===Regular events===
* The New Year's Gala Concert of the Symphonisches Blasorchester Obere Nahe e.&nbsp;V. (wind orchestra) has been seeing the town into the New Year culturally since 1991.
* The International Trade Fair for Gemstones, Gemstone Jewellery and Gemstone Objects is held yearly in September and October (''see also below'').
* The regional consumer fair, better known as ''Idar-Obersteiner Wirtschaftstage'', was created by the ''Wirtschaftsjunioren Idar-Oberstein 2003'', and is growing into a true success story. It was organized and staged from 2003 to 2005 by the ''Wirtschaftsjunioren''.
* The ''Deutsche Edelsteinkönigin'' (“German Gemstone Queen”) is chosen every other year from the region of the ''Deutsche Edelsteinstraße'' (“German Gem Road”).
* The ''Spießbratenfest'' (“Spit Roast Festival”) has been held since 1967 each year from the Friday to Tuesday that includes the last Sunday in June. It is said to be the biggest folk festival on the Upper Nahe.
* The ''Kinderkulturtage'' (“Children’s Cultural Days”) have been being held for several years now as a successor festival to the ''Kinderliederfestival'' (“Children’s Song Festival”). There are 15 to 20 events for children, youth and those who are young at heart.
* Each year in early June, the ''Jazztage'' (“[[Jazz]] Days”) are held. Appearing here are regional and national jazz greats on several stages in the Idar [[pedestrian precinct]].
* [[Diamond]] grinders, facet and surface grinders and agate grinders demonstrate the most varied working techniques within the framework of the ''Deutscher Edelsteinschleifer- und Goldschmiedemarkt'' (“German Gemstone Grinders’ and Goldsmiths’ Market”). [[Goldsmith]]s and jewellery designers allow a look at their creative work in Oberstein's historic town centre below the ''Felsenkirche''.
* The ''Kama Festival'' was held from 1991 to 2007 on the lands of the Kammerwoog Conservation Area at [[Whitsun]]. It was the biggest open-air festival in Idar-Oberstein. The last festival took place in much reduced form in 2008.

===Culinary specialities===
[[File:Idarer Spiessbraten.JPG|thumb|Idarer Spießbraten]]
[[File:Obersteiner Spiessbraten.jpg|thumb|Obersteiner Spießbraten]]

====''Spießbraten'' (spit roast)====
A distinction is made between ''Idarer Spießbraten'' and ''Obersteiner Spießbraten''. The former is a kind of [[Schwenker|''Schwenkbraten'']], whereas the latter is a kind of rolled roast. ''Spießbraten'' is rooted fast among Idar-Oberstein's and the surrounding region's culinary and cultural customs.

When making the more often consumed ''Idarer Spießbraten'', the meat – originally [[prime rib]], today often also [[roast beef]] or pork neck – is laid the day before cooking in raw onions, salt and pepper. The onions are good to eat while cooking at the fire with a beer. Locals favour beechwood for the fire, to give the roast its traditional flavour.

The variations on the ''Spießbraten'' recipe are also the subject of the town's slogan, which bears witness to a patronizing cosmopolitanism<!--not at all sure if those 2 words are right-->: ''Rossbeff fa die Idarer, Kamm fa die Uwersteener und Brot für die Welt'' – dialectal German for “Roast beef for the Idarers, pork neck for the Obersteiners and bread for the world.”

====''Fillsel''====
This is toast, minced meat, diced bacon, [[leek]], eggs, salt and pepper.

====''Gefillte Klees'' (filled dumplings)====
This is coarse potato dumplings (made from raw potatoes) filled with ''Fillsel'' with a bacon sauce.

====''Kartoffelwurst'' (potato sausage)====
Also dialectally called ''Krumbierewurscht'', this was formerly “poor people’s food”, but today it is a speciality. Potatoes, pork, beef and onions are put through the [[mincer]] and seasoned with [[Satureja|savoury]], pepper and salt. It can be fed into the traditional gut, preserved in a jar or even eaten straightaway.

====''Murde on Klees'' (carrots and dumplings)====
This is raw potato dumplings cooked and served together with carrots (sometimes known in German as ''Mohrrüben'', or dialectally in Idar-Oberstein as ''Murde'') and pickled or smoked pork.

====''Riewe on Draehurjel''====
This is [[beetroot]]s with roast blood sausage.

====''Dibbelabbes''====
This is made by roasting ''Kartoffelmasse'' (potatoes, bacon, eggs, flour, salt and pepper) in a ''Dibbe'' (cast-iron roasting pan).

====''Schaales''====
This is ''Kartoffelmasse'' (the same as for ''Dibbelabbes'') baked in a ''Dibbe'' in the oven with dried meat.

==Economy and infrastructure==
All together<!--NO, THAT IS NOT MISSPELT! “Altogether” has an altogether different meaning.-->, Idar-Oberstein has roughly 219.3&nbsp;ha of land given over to commerce. Three other areas in town, Dickesbacher Straße, Finkenberg Nord and Am Kreuz, hold a further 28&nbsp;ha in reserve for economic expansion. The town also has at its disposal the rezoning area ''Gewerbepark Nahetal'' in the outlying centre of Nahbollenbach, comprising 23&nbsp;ha.

The ''Bundesverband der Diamant- und Edelsteinindustrie e.&nbsp;V.'' (“Federal Association of the Diamond and Gemstone Industry”) has its seat in Idar-Oberstein. It represents the industry's interests in dealings with lawmakers as well as federal, state and municipal representatives. It advises members in areas such as environmental protection, problems in [[competition (economics)|competition]], questions of nomenclature and so forth, and makes the necessary contacts as needed. To promote the designing and quality of jewellery and gemstones, the Association created the international competition revolving about the German Jewellery and Gemstone Prize.
[[File:Edelsteinboerse io.jpg|thumb|The ''Börsenhochhaus'': View over Schleiferplatz]]
The ''Deutsche Diamant- und Edelsteinbörse e.&nbsp;V.''  (“German Diamond and Gemstone Exchange”) was opened in 1974 as the world's first combined exchange for diamonds as well as coloured gemstones. It is one of the 25 exchanges in the [[World Federation of Diamond Bourses]].

The firm Klein & Quenzer was among the best known producers of [[costume jewellery]] before it rose to become the biggest manufacturer of German medals and decorations during the two world wars.

The ''Wirtschaftsjunioren Idar-Oberstein'' were founded in 1972. Entrepreneurs and senior management join in this organization for economic, cultural and social purposes in the region.

The cookware manufacturer Fissler has its headquarters in town. The company became well known for its invention of the mobile [[field kitchen]] in 1892. Giloy und Söhne, one of Europe's biggest diamond jewellery manufacturers, has its headquarters here, too.

For more than 20 years now, the International Trade Fair for Gemstones, Gemstone Jewellery and Gemstone Objects (“Intergem”) has been held in Idar-Oberstein. The fair takes place at the ''Jahnhaus'' in the constituent community of Algenrodt, although as of 2008, a move to the planned exhibition hall in the new Nahetal commercial park (former US Army storage depot Nahbollenbach) was being considered.{{citation needed|date=March 2015}}

The ''Idar-Obersteiner Wirtschaftstage'' (“Economy Days”), initiated by the Idar-Oberstein Economic Promotional Association, are regarded in and around Idar-Oberstein as a regional fair.

===Natural gemstone deposits===
Gemstones from throughout the world are to be found in Idar-Oberstein, but the whole industry was begun by finds in the local area. These include [[agate]], [[jasper]] and [[rock crystal]].

===Garrison===
[[File:Klotzbergkaserne.jpg|thumb|''Klotzbergkaserne Idar-Oberstein'']]
Since 1938, Idar-Oberstein has been a [[garrison]] town. During the 19th and 20th centuries, [[France|French]] and German soldiers in turn were stationed here. With the coming of the [[Wehrmacht]], new barracks were built. After the [[Second World War]], the ''Straßburgkaserne'' (“Strasbourg Barracks”) were at first used by the [[United States Army]]. French troops were stationed at the ''Klotzbergkaserne'', and then as of 1956, the [[Bundeswehr]] [[artillery]] school. This moved in the late 1960s to the newly built ''Rilchenbergkaserne''. Since that time, thousands of artillerymen have undergone their basic and advanced military training here. In September 2003, new boarding school buildings and teaching rooms were dedicated so that today's artillery school has at its disposal both up-to-date lodging capacity and a training centre with all the modern equipment. Included among the teaching methods are audio, video and simulation techniques. Stationed at the ''Klotzbergkaserne'' until 31 March 2003 was the ''Beobachtungspanzerartillerielehrbataillon'' (“Observational Armoured Artillery Teaching Battalion”) 51, after whose dissolution in the course of Bundeswehr reform, the language training centre for officer cadets moved in. For businesses in Idar-Oberstein and environs, the Bundeswehr is a major economic factor as both an employer and a client. Since 1988, there has been a “sponsorship” between the town of Idar-Oberstein and the artillery school, and to highlight the relationship, town council decided in 1988 to put up a second roadsign that read “''Hauptstadt der deutschen Artillerie''” (“German Artillery Capital”). After objections from local business, among others the local [[chamber of commerce]], and from some of the townsfolk, too, it was decided that the town would not go to the trouble of installing such signs after all.<ref>JungleWorld: [http://www.beucker.de/1998/juwo98-06-10.htm ''Bum-Bum-Helau&nbsp;– ein Schuß ins Knie'']; Ausgabe vom 10. Juni 1998</ref> In 2006, the officer cadet battalion was disbanded.

===Transport===
[[Idar-Oberstein station]], as a [[Regional-Express]] and [[Regionalbahn]] stop, is linked by way of the [[Nahe Valley Railway]] ([[Bingen am Rhein|Bingen]]–[[Saarbrücken]]) to the [[Saarland]] and the [[Frankfurt Rhine Main Region]]. The ''Rhein-Nahe-Express'' running the [[Mainz]]-Saarbrücken route serves the station hourly. Every other one of these trains goes through to the [[Frankfurt (Main) Hauptbahnhof|main railway station]] in [[Frankfurt]] with a stop at [[Frankfurt Airport]]. Formerly, fast trains on the Frankfurt-[[Paris]] route had a stop at Idar-Oberstein.

Local transport in Idar-Oberstein was run from 1900 to 1956 by [[tram]]s, and from 1932 to 1969 by [[trolleybus]]es. Today's network is made up of six bus routes run by the ''Verkehrsgesellschaft Idar-Oberstein [[GmbH]]'', which belongs to the Rhenus Veniro Group. Furthermore, Idar-Oberstein is the starting point for Regio bus routes to [[Baumholder]] and [[Birkenfeld]]. There is also a direct bus link to [[Frankfurt-Hahn Airport]]. The most important road link in town is ''[[Bundesstraße]]'' 41; although there is no direct [[Autobahn]] link, the [[Bundesautobahn 62|A&nbsp;62]] ([[Kaiserslautern]]–[[Trier]]) can be reached through [[interchange (road)|interchange]]s at Birkenfeld (B&nbsp;41) or [[Freisen]].

==== Highway over the Nahe ====
[[File:Nahehochstrasse.jpg|thumb|Highway over the Nahe in Oberstein]]
In the 1980s, the river Nahe was covered over with a four-lane highway, ''Bundesstraße'' 41, mentioned above, putting the river underground, beneath the town. This is unique in Germany and has greatly changed the town's appearance in this area. The first plans for this development (officially the ''Nahehochstraße'') lay before planners as early as 1958, but they set off a wave of criticism that was felt far beyond the town's limits. On the theme of “Highway over the Nahe – yes or no”, [[Südwestfunk]] broadcast a [[talk show]] in the 1980s. The project was meant to relieve traffic congestion in the inner town on the B&nbsp;41, which at the time ran through what is now a narrow pedestrian precinct through the middle of the Old Town. Work on the project began in 1980, and lasted five years, after which the ''Nahehochstraße'' was at last completed. The Nahe had thus been channelled into a two-kilometre-long tunnel. A timber-frame house nearby, the ''Sachsenhaus'', was torn down and put into storage, its pieces numbered. Its reconstruction has been indefinitely postponed. In 1986, the ''Naheüberbauung'', as it is commonly known, was opened to traffic. For its 20th anniversary, there was an exhibition at the Idar-Oberstein ''Stadthaus'' (civic centre) with photo galleries about the planning, building and completion of the project.

For its efforts, Idar-Oberstein won an award in 1988 in a contest staged by German town planners: First Prize for Most Consequential Blighting of an Historic Townscape.<ref>Second place went to [[Itzehoe]], where in the 1970s, the historic town centre was renovated and the bow of the river [[Stör]] running through it was filled in and built over. cf. Dagmar Vorbeck, in: Stadt Itzehoe (Hrsg.): ''Itzehoe. Geschichte einer Stadt in Schleswig-Holstein'', Bd.&nbsp;II, S.&nbsp;390.</ref>

====I-O/Göttschied Airfield====
Idar-Oberstein/Göttschied Airfield lies north of the town between the constituent community of Göttschied and the municipalities of Gerach and Hintertiefenbach at an elevation of 480&nbsp;m above [[sea level]] (1,575 feet). Its [[ICAO location indicator]] is EDRG. The grass [[landing strip]]'s orientation is 06/24, and it is 650&nbsp;m long and 50&nbsp;m wide. The allowable landing weight is 2&nbsp;000&nbsp;kg; however, with PPR (“prior permission required”), aircraft of up to 3&nbsp;700&nbsp;kg may land. The airport is designed for [[helicopter]]s, [[motor glider]]s, [[Glider (sailplane)|gliders]], [[ultralight]]s and, also with PPR, [[skydivers]].

Offered here on weekends are sightseeing flights by motorized aircraft, motor glider, glider and ultralight.

* The ''KMT-Klinik'' is a clinic for [[bone marrow]] transplants and [[haematology]].
The [[University of Mainz]] specialist and [[teaching hospital]], which grew out of the former Municipal Hospitals, is part of the ''Saarland Heilstätten'' (a group of hospitals) – even though it is not in the Saarland – and has some 500 beds and 1,000 employees, as well as departments for [[General surgery|general]], [[Abdominal surgery|abdominal]] and [[vascular surgery]], [[gynaecology]] with [[obstetrics]], [[internal medicine]] with [[gastroenterology]], [[nephrology]], [[diabetology]] and [[Kidney dialysis|dialysis]], [[Medical imaging|diagnostic and interventional radiology]], [[cardiology]], bone marrow transplantation and haematology/[[oncology]], [[neurology]] with a [[stroke]] unit and [[neurosurgery]], [[psychiatry]] with [[child and adolescent psychiatry]] and [[psychotherapy]], [[paediatrics]] with [[neonatology]], [[radiation therapy]], [[trauma surgery]] and [[urology]] as well as wards for [[ophthalmology]] and [[otorhinolaryngology]]. Excluded from this is a [[Gerontology|geriatric]] rehabilitation clinic in Baumholder. There is also no [[nursing school]].

===Education===
Idar-Oberstein is home to every kind of educational institution, and since 1986, it has been a ''Hochschule'' location. The internationally renowned programme of [[Jewelry design|Gemstone and Jewellery Design]] of the Faculty of Design at the [[University of Applied Sciences Trier]] is the only place in Europe where artistically-scientifically oriented studies in design in the field of gemstones and jewellery can be undertaken. It is found together with the professional school centre and the town's only [[Realschule]] at the ''Schulzentrum Vollmersbachtal''. There are several [[Hauptschule]]n throughout the town. There are moreover four [[Gymnasium (school)|Gymnasien]]: the Göttenbach-Gymnasium and the Gymnasium an der Heinzenwies can be attended beginning at the fifth class, while the Technisches Gymnasium and the [[Wirtschaftsgymnasium]] only admit students beginning in the eleventh class.

* The [[University of Mainz]] maintains the ''Institut für Edelsteinforschung'' (Institute for Gemstone Research) in Idar-Oberstein. The Gemstone Research Department belongs to the subject area of [[mineralogy]] in the Faculty of [[Earth Sciences]].
* The University of Applied Sciences Trier offers at its Idar-Oberstein location a programme in Gemstone and Jewellery Design.
* The [[Deutsche Gemmologische Gesellschaft]] e. V. (“DGemG”, German Gemological Association) was founded in 1932 and developed into an internationally renowned institution of technical-scientific [[gemmology]]. Successful participation in the DGemG courses in gemmology and diamond studies leads to diploma certification of performance on examinations that qualify the graduate to apply for membership in the DGemG (F. G. G. – the F is for the German word ''Fachmitgliedschaft'', or “professional membership”). Thus far, more than 30,000 participants from 75 countries have attended the DGemG programme, which is designed with the demands of the gemstone and jewellery industry in mind.
* The Forschungsinstitut für mineralische und metallische Werkstoffe Edelsteine/Edelmetalle GmbH (FEE; Research Institute for Mineral and Metallic Materials Gemstones/Precious Metals), too, has its seat in Idar-Oberstein. The FEE specializes in growing crystals and manufacturing optical elements for [[laser]]s.
* The Deutsche Diamantprüflabor GmbH (DPL; German Diamond Testing Laboratory) has been assessing since 1970 the quality of [[cut diamonds]]. As the first laboratory of its kind in Germany (and second in the world), the DPL has been officially certified by the German Testing Accreditation System in [[Berlin]] as being able to carry out competent quality assessment of diamonds with regards to colour, size, cut and proportion in accordance with internationally recognized standards.

In 1997, a [[Lufthansa]] [[Airbus]] A319-114 (registration number D-AILN) was christened “Idar-Oberstein”. It entered service on 12 September of that year. The aircraft was for a time leased to the firm [[Germanwings]], but has since been reincorporated into Lufthansa's fleet.
