Gernot Weber – Lapidary, Gemstone Cutter

If this great selection of extravagant gemstones is to continue to find its way into Constantin Wild’s treasure chamber, one man is indispensable: Gernot Weber. As a gemstone cutter he carries the heritage of the gemstone metropolis within him.

JOURNAL: Idar-Oberstein is regarded as the absolute gemstone metropolis. How did that come to be?

Gernot Weber: Agates were discovered here for the first time in the 15th century. The wild Idar stream, which flows right through the town, quickly gave rise to numerous cutting-shops, in which my forefathers were able to process the stones. Later, jasper and rock crystal were discovered too. When the domestic deposits began to decline at the beginning of the 19th century, the people of the Hunsrück set off out into the great wide world and discovered many other kinds of stone there. But the stones were always processed back at home.
