A cool specimen of high quality dioptase crystals from Mindouli, Congo - Brazzaville. They are strongly lustrous with a gorgeous dark emerald-green color and very sharp, well terminated crystal. The quality is superb - the crystal is gemmy at the tip with marvelous neon-green nuances. It looks better in person. In very good condition - some micro nicks. On acrylic base.

Splendid dioptase!
