Several dozen Dioptase crystals rest on the calcareous base of this hand specimen. These crystals are generally in very good condition- damage is minimal- and reach lengths of about 0.3" (8 mm). All have excellent trigonal prismatic form and show the classic deep, emerald-green color and vitreous luster of the specie. All are dimly to moderately transparent, with the larger crystals containing many internal fractures. A few stray calcite "dogtooth" crystals rest on the base.
