- Calcite, Quartz (Var: Amethyst)
- Large Cabinet, 17.0 x 12.2 x 8.8 cm
- Idar-Oberstein, Hunsruck Mts, Rhineland-Palatinate, Germany
This is a fine, dramatic and probably old large cabinet specimen of calcite on amethyst from the ancient workings of quartz in Idar-Oberstein, used for centuries for carving and lapidary art. Still today, the world center of the highest end of the lapidary crafts is based in Idar-Oberstein, though stone to work on is now imported from elsewhere. This is a striking and beautiful pocket in basalt of lightly hematite-tinted amethyst crystals hosting a dense cluster of glassy, colorless calcite crystals to 2.5 cm. Ex.
