Exceptional, 2.9 cm doubly-terminated Dioptase from an older, classic locality. The luster is excellent, and the color a deep, beautiful green. One termination is partially contacted, but to find a DT Dioptase of this size so complete, and aesthetic, is unusual. This is a dominating, HUGE single crystal and makes for a full-sized thumbnail of some impact. It is a very fat, robust crystal that LOOKS like Tsumeb material (which would be thrice the price) .
