Gorgeous cluster of gemmy Dioptase crystals up to 16mm from Pimbi hill, Mindouli, Republic of Congo - Brazzaville. This specimen was mined more that 30 years ago by a geologist and stored. The crystals are strongly glassy lustrous with gorgeous dark emerald-green color and very sharp, perfectly terminated crystals. The quality is superb - the crystals have gem tips with marvelous neon-green nuances. Better in person. In very good condition – some small nicks and outside edge contacts. On acrylic base.

Fascinating Dioptase!
