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 filled with sharp, rich emerald green color Dioptase crystals with a secondary coating of smaller Dioptase crystals forming a very attractive overall specimen. The largest crystal meaures a full 2.3 cm.
