- Dioptase on Calcite with Duftite
- Small Cabinet, 5.4 x 4.2 x 2.7 cm
- Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Dioptase on Calcite is one of the most attractive and desirable of all the Tsumeb combinations. These Dioptases are a rich emerald green, and are some of the gemmiest Dioptase crystals I have seen. Much more so than the pics can portray, in fact. The luster on both the Dioptases and the Calcite rhombs is excellent. There are even micro crystals of olive green duftite as a bonus. This choice small cab is highly representative for both the species and location.
