Dioptase is known from a few world localities in superb quality specimens, but recently there was a find of new material in the Pool Region of the Congo. These specimens show great color, with larger sized crystals and EXCELLENT gemminess. This particular specimen is comprised of very sharp, highly lustrous, gemmy, rich emerald green color Dioptase crystals forming a very attractive thumbnail specimen. This find seemed to be somewhat limited, and hopefully will produce more of this SUPERB quality Dioptase. With the price of Tsumeb Dioptase specimens rising daily, this is a great opportunity to snag a "Tsumeb"-type quality specimen of this species for a fraction of the price. A gorgeous thumbnail of this exciting new material. Ex. Brian Kosnar Collection.
