Marvelous Dioptase crystals from this great locality - Tsumeb Mine, Namibia. The specimen was found 1988. The crystals are brilliantly lustrous with gorgeous dark emerald-green color and very sharp, perfectly terminated crystals to 14mm. The main crystal is doubly terminated. The quality is superior – very fresh and shiny. The crystals are gemmy with marvelous neon green nuances. The small base is formed by white crystals with minor apple-green Duftite. Some nicks and contacts. On acrylic base.

Fascinating!
