Gorgeous specimen of gemmy Dioptase crystals decorating white Calcite from this famous locality – Tsumeb Mine, Namibia. The Dioptase crystals are brilliantly lustrous with intense emerald-green color up to 10mm. Many of them are doubly terminated. The crystals are gemmy with marvelous neon green nuances. They sit very well isolated and the white Calcite base gives a strong contrast. In superb condition. On acrylic base.

Magnificent!
