This single Tanzanite crystal is in good condition, showing minor damage along one acute edge, and has reasonably good orthorhombic prismatic form. Its uniform violet color suggests that it has been heat-treated, and its vitreous luster is standard for the specie. Though transparent and moderately clear, it contains many internal fractures (most likely caused by the heat-treatment). There is no base rock present.
