A gorgeous specimen of gemmy dioptase crystals decorating snow white calcite base from this famous and classic locality – Tsumeb Mine, Namibia. The dioptase crystals are brilliantly lustrous with an intense emerald-green color to 12mm. They are gemmy with marvelous neon green nuances. They sit well isolated and the white rhombohedral calcite crystals give a strong contrast. In very good condition – some small nicks and outside edge contacts. On acrylic base.

Magnificent!
