Top quality Dioptase specimen from this great locality - Tsumeb Mine, Namibia. The crystals are brilliantly lustrous with gorgeous dark emerald-green color and very sharp, perfectly terminated crystals. The quality is superior – very fresh and shiny. The crystals are gem with marvelous neon green nuances. Parts of the Dioptase are covered by micro colorless Calcite crystals, which add superb contrast and sparkling appearance. Some minor Duftite is seen too. In very good condition – some small nicks and contacts.

Exceptional!
