A neat specimen of dioptase crystals from the famous Tsumeb Mine, Namibia. The crystals grow one atop another in a strange structure. They are well terminated, lustrous, with an intense emerald-green color and sharp. The quality is very good. The crystals are gemmy with marvelous neon green nuances. In very good condition – some small contacts. On acrylic base.

Cool!
