Beautiful specimen of Dioptase and Duftite decorating colorless Calcite from this famous locality – Tsumeb Mine, Namibia. The Dioptase crystals are small but brilliantly lustrous with intense emerald-green color. The crystals are gemmy with marvelous neon blue and green nuances. Lighter green Duftite grow above. The sharp rhombohedral Calcite crystals are transparent and lustrous. The contrast is very strong with wonderful colorfulness. In excellent condition – some small nicks.

Fantastic!
