A gorgeous specimen of dioptase crystals from Reneville, Kindanba District, Pool Department, Congo - Brazzaville. The crystals are strongly glassy lustrous with a rich dark emerald-green color and very sharp, perfectly doubly terminated crystals. The quality is superb - the crystals are well isolated and they contrast strongly on the white base. Better in person. In excellent condition – some minor nicks and outside edge contacts. On acrylic base.

Fabulous!
