This thumbnail piece consists of a single Topaz crystal that is in excellent condition, though its base denotes basal parting. Its orthorhombic prismatic form is likewise excellent, showing good symmetry along one plane when viewed from above. Its pale brown color with a hint of pink and its vitreous luster are standard for pieces from its locality, but a few termination faces (again, symmetrical along the aforementioned plane) have a matte luster. There is no host rock, and the crystal is attached to a flat, acrylic base with an adhesive putty.
