A gorgeous specimen of gemmy dioptase crystals over white calcite from this great locality - Tsumeb Mine, Namibia. It displays fine dioptase crystals to 12mm. They are brilliantly lustrous with rich and saturated emerald-green color, and very sharp, perfectly terminated crystals. Many are doubly terminated. The quality is superior – very fresh and shiny. The crystals are gemmy with marvelous neon green nuances. It displays attractively all over 360 degree. In good condition – some contacts. On acrylic base.

Outstanding and beautiful!
