Exceptional top Dioptase specimen with striking gem crystals from the type locality for the species - Altyn-Tyube deposit, Kazakhstan. The Dioptase crystals are up to 15mm, brilliantly lustrous with dark and saturated emerald-green color and very sharp, perfectly terminated crystals. Some crystals are doubly terminated. The quality is superior. The crystals are gem with marvelous neon green nuances. The Dioptase crystals are very well isolated and form superb focal points with beautiful display.  Some small colorless Calcites are seen too.  In excellent condition – one crystal has small imperfection (the last 2 detail photos).

Killer world grade quality Dioptase piece!
