Description:Dioptase is known from a few world localities in superb quality specimens, but recently there was a find of new material in the Pool Department of the Congo (Brazzaville). These specimens show great color, with larger sized crystals and good gemminess. This specimen hosts sharp, thick / stout, rich emerald green color Dioptase crystals wedged between host rock matrix creating an attractive specimen. The piece is in great shape overall with excellent color and luster, but there are some contacted crystals, so it's not 100% damage free. The largest Dioptase measures 1.7 cm. 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"-like specimen of this species for a fraction of the price.
