Dioptase on Calcite
Miniature, 4.1 x 2.3 x 1.8 cm
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia

Glorious pair of superb Dioptase crystals on a layer of fluorescent Calcite. Each of the major Dioptases is over 1.6 cm, and the mirror-like luster and the gemmy green fire cannot be beat by those from other locales. They are so good, in fact, that in the pics it looks like the surfaces of the crystals are pitted, yet all you are doing is looking down into the crystals seeing the green fire beneath the glassy surface. A superb miniature.
