Several tightly-arranged Dioptase prisms rest on the quartz and calcite base of this hand specimen. These crystals are generally in very good condition, showing damage only around the edges of the cluster, and reach lengths of nearly 0.4" (1 cm). Their trigonal prismatic form is excellent, and their intense emerald-green color is standard for their specie. All have a slightly dull, pearly luster and are transparent and dimly to moderately clear, containing internal fractures and inclusions. A few broken calcites are also present on the piece- one of these contains some inclusions in the form of a few tiny Dioptases!
