Dioptase, Calcite
Small Cabinet, 5.1 x 4.4 x 3.6 cm
Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia

A remarkably pretty Tsumeb dioptase specimen, not just because of the brightness and isolation of the dioptase crystals themselves (to 1 cm), but because of the perfect calcite rhomb perched at the top of the specimen. 5.1 x 4.4 x 3.6 cm
