Five visible Topaz crystals rest on the pale brown host rock of this hand specimen. All are in very good conditionn, showing little damage. The largest of these measures 0.8" (2.0 cm) long and like one of the others is rather heavily intergrown with host rock and very warped. The remaining crystals, however, are of gem-quality and have excellent orthorhombic prismatic form, with well-defined edges and clean faces. They all possess a pale brown color and a bright, vitreous luster, and are transparent and exceptionally clear. They are accompanied by a few tiny pseuobrookite octahedrons that are also embedded in the host rock.
