Gem Topaz (Direct Mine source) – Location: Thomas Range Juab Co. Utah. Miniature (see photo for more details). Here we have a nice cluster of amber sherry colored topaz crystals from a relatively new topaz locality in the Thomas Range that we as topazminer own and operate in the Thomas Range in western Utah. Here we have an aesthetic cluster of gemmy topaz crystals that are well-formed sharp and have a beautiful amber sherry color along with a glassy luster. The crystals are of gem quality. The crystals are a black color with a bright metallic luster.
