Outstanding quality cluster of Dioptase crystals from Pimbi hill, Mindouli, Republic of Congo - Brazzaville. This specimen was mined more that 30 years ago from 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 are gemmy with marvelous neon-green nuances. It displays beautifully all over 360 degree. In very good condition – some small nicks and contacts.

Killer Dioptase!
