Beautiful glassy, transluscent dioptase crystal with ball-like aggregates of shattuckite, on calcite crystals that are partially coated with chrysocolla. Near one end of the main dioptase crystal (1.4 cm in length) there is a small second intergrown dioptase crystal, giving it a nice accent. The shattuckite balls are small (ca 1 mm) but there are in fact small shattuckite on the main dioptase, and even a couple occurring as inclusions in it! (You need at least a loupe to see this.) The dioptase crystals are pristine and super sharp, with wonderful colour.
