Nestled within old-growth forests along the picturesque river Nahe and the rocky faces of the Hunsrueck Mountains lies Idar-Oberstein and the Gemstone Road. For more than 500 years, this quaint corner of southwestern Germany has revolved around gemstones. Small though it is, this town has built an international reputation for gemstone cutting, carving, and polishing.

History

What is today the serene Hunsrueck mountain range once raged with earth-changing dynamism. During the Permian geologic period, lava flows sprung forth from below the earth’s crust, trapping gasses, which began to form minerals as they cooled. This phenomenon resulted in rich and beautifully layered mineral deposits of jasper, agate, amethyst, carnelian, and chalcedony.

The unique mineral wealth of the land sparked mining efforts beginning in the Middle Ages, including the start of mechanized mining more than 500 years ago. A thriving gemstone community sprung up in response in what is now Idar-Oberstein, attracting stone cutting, polishing, and carving tradespeople. By the time local gem resources had been exhausted in the 1800s, the area enjoyed wide renown as one of the gemstone-cutting capitals of Europe.

Lore

Lore from the 12th Century ties the original discovery of gemstones in the Hunsrueck Mountains to a tale of love and murder. The story tells that Count Wyrich of Oberstein and his brother Emich were smitten with the same woman, Bertha of Lichtenberg. When Wyrich’s anger and jealousy at Emrich finally boiled over, he tossed his brother out a castle window to his death. After years in exile, the repentant Count returned to build a church into the cliff from which Emich had plummeted to his death. The legend holds that during excavations for the church, the first deposits of amethyst, agate, and jasper came to light, marking the start of the Idar-Oberstein gemstone industry.

Global Connections

Responding to the shortage of gems, miners and tradespeople from the Hunsbrueck region spread across the globe in the mid-1800s in search of new raw material to cut, carve, polish, and trade. One of the earliest and most profitable of these destinations was Brazil, whose gem and mineral deposits are among the richest in the world. This emigration wave also extended to Asia, Africa, and Australia, opening trade channels for Australian opals, moonstone from Ceylon, African tiger’s eye, and many others. Though born out of the hardship of resource scarcity, the resulting international gemstone trade network flowing toward Idar-Oberstein has meant access to varied and world-class gem specimens and enabled incredible craftsmanship legacies to flourish here for generations. This tiny town remains a highly-renowned center for gemstone cutting, carving, and polishing.

The Gemstone Road (Edelsteinstraße)

Today, Idar-Oberstein and its neighbors proudly uphold the region’s gemstone-centric way of life. The area boasts more than 600 gem shops, the German Gemstone Museum, historical and trade-related attractions, and even its own “Gemstone Queen.” Here are a few highlights from the Gemstone Road.

The German Gem Museum (Die Deutsche Edelstein Museum)

Visitors behold a dazzling array of rough and polished gems and an impressive sculpture gallery. About 90% of the treasures on exhibit are on loan from “grinder families” with enduring ties to the area. The collection includes specimens of nearly every gemstone represented in raw and cut or polished forms.

Steinkaulenberg

This vast maze of retired mining tunnels is an adventurous way to see geology and get closer to mining history. In fact, it’s the only site in Europe where one can tour a real mine. Caverns feature agate, amethyst, smoky quartz, calcite, and mystic pools, illuminated to stunning effect..

CHAPEL IN THE ROCKS (FELSENKIRCHE)

This iconic medieval church, linked to the tale of Count Wyrich above, is set high into a cliff face above Oberstein. To enter, visitors must take a tunnel and ascend 230 steps. The chapel houses a crucifix of natural, locally-sourced agate, an organ more than 250 years old, a Gothic baptismal font, and a burbling natural spring.

WEIHER-SCHLEIFE GRINDING MILL

Before electricity, rotary cutting or polishing depended on some force great enough to propel a massive wheel. The steady waters of the Nahe river, which flows through Idar-Oberstein, supported a mill-powered stone cutting and polishing industry adjacent to mines, maximizing efficiency. To cut or polish using a traditional setup, workers laid on angled planks in front of enormous limestone wheels sluiced with water. These days, Idar-Oberstein’s artisans use the most advanced lapidary tools, but for the curious visitor, the Weiher-Schleife grinding mill keeps the pre-electric tradition alive and holds demonstrations.

ATELIER MUNSTEINER

Though technically off the “Gemstone Road” path, no trip to the region could be complete without paying homage to the “Picasso of Gems” in nearby Stipshausen. Atelier Munsteiner stands out as a uniquely modern and innovative gemstone cutting house. Lapidary Bernd Munsteiner, a third-generation gemstone-cutter, learned the trade from his father, Viktor. He then built upon tradition to change the gemstone world forever by pioneering the “fantasy cut.” His cutting style uses angular or soft, organic forms cut into transparent gems, filling stones with color and light in surprising and evocative ways. This breakthrough opened up a new way of cutting, inspiring the next generation of lapidary professionals to continue innovating with daring and creative cuts.
