Outstanding world grade quality specimen of Dioptase with striking gemmy crystals from the type locality of Altyn-Tyube deposit, Kazakhstan. The Dioptase crystals are up to 10mm big, lustrous with dark emerald-green color and very sharp, perfectly terminated crystals. Some crystals are doubly terminated. The quality is superior. The crystals are gemmy with marvelous neon green nuances. The sparkling colorless Calcites base underlines them strongly. Displays beautifully all over 360 degree.

Absolutely amazing top Dioptase specimen!
