Gorgeous specimen of gemmy Dioptase crystals from this great locality - Tsumeb Mine, Namibia. It displays an excellent specimen with crystals up to 16mm. They are brilliantly lustrous with dark emerald-green color and very sharp, perfectly terminated crystals. Many are doubly terminated. The quality is superior – very fresh and shiny. The crystals have gem areas with marvelous neon green nuances. The white base underlines them strongly. Apple-green Duftite are seen too. In superb condition.

Outstanding and beautiful!
