This thumbnail specimen consists of a cluster of 7 or 8 Dioptase prisms that rest on a pale-brown, quartz encrusted base. These crystals are generally in good condition- those on the edges are damaged, but the rest are intact- and reach lengths of nearly 0.4" (1 cm). All have excellent trigonal prismatic form and show the classic, deep emerald-green coloration of the specie. Their luster is vitreous and all are transparent and dimly clear, containing many flaws.
