A cluster of 3 or 4 Topaz crystals make up the bulk of this thumbnail specimen. All but 2 of these crystals are broken and incomplete, but the intact ones are in excellent condition, showing no damage. Both of these crystals have dimensions of about 0.9 x 0.3 x 0.2" (2.3 x 0.8 x 0.2 cm), though one is slightly larger. Their orthorhombic form is excellent, with well-defined edges and very clean faces that possess the standard vitreous luster. Their golden-brown color is standard for Topaz from this locality, and they are transparent and very clear at their terminations, though both tend to cloud a bit with inclusions towards their bases. Only small amounts of the rhyolite host rock are present, mostly attached to the broken crystals. The piece is affixed to a flat, square acrylic base with a removable putty.
