Several small Tanzanite crystals extend from the broken Tanzanite base of this thumbnail specimen. These crystals are very small, ranging from 2 mm to 0.4" (1 cm) in length, and are generally in good condition, though 2 are noticeably damaged. The largest crystals are somewhat intergrown, but all have good orthorhombic prismatic form, with well-defined edges and clean faces. The piece has been heat-treated, so their moderate blue-violet color is nearly uniform. Their luster is vitreous, and all are transparent and quite clear, containing a few internal fractures that are mainly concentrated at their bases. They rest on a base of broken, heavily-fractured Tanzanite.
