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. The best of these specimens show great color, with larger sized crystals and excellent gemminess. This particular specimen hosts sharp, rich emerald-green color Dioptase on rare contrasting soft blue color Plancheite. This find seemed to be somewhat limited, and hopefully will produce more of this superb Dioptase.
