Locality: Tarryall Mtns., Park Co., Colorado, United States
Formula: Al₂SiO₄F₂
Availability: Sold
Size: 3 x 3 x 2.5 cm - Thumbnail

Faint green, gemmy, textbook Topaz crystal showing at least eight faces some with shallow striations. An interesting feature at the intersection of the two main faces is the serrated termination caused by micro striations on both of the faces. You can feel this when your fingernail is slid down the edge. This locality is probably the most well-known and collected area in Colordao for Topaz.
