An exceptional specimen of gemmy dioptase crystals and duftite, decorating colorless calcite crystals from this famous and classic locality – Tsumeb Mine, Namibia. The dioptase crystals are brilliantly lustrous and strongly light reflective, with an intense emerald-green color, up to 10mm. Many of them are doubly terminated.  They are gemmy with marvelous neon green nuances. The small, sharp rhombohedral calcite crystals are white and lustrous. Small apple-green duftite spheres grow above the calcite. It displays beautifully all over 360 degree. The contrast is very strong with wonderful colorfulness. Better in person. In very good condition – some small nicks.

Astounding Tsumeb combo!
