Fantastic specimen of Dioptase from this great mine - Tsumeb Mine, Namibia. It comes from the collection of Maurizio Sprovieri, Italy with label. The Dioptase crystals are up to 24mm, extremely brilliant and lustrous with a very rich emerald-green color and sharp, perfectly terminated crystals. Some of them are doubly terminated. The quality is superb with very fresh appearance. The crystals are slightly gemmy with marvelous blue-green nuances. Some contacts. On acrylic base.

Mesmerizing Dioptase!
