| This beautiful spray of sherry-colored topaz crystals is from the Thomas Range in Utah. Sherry-colored crystals are found in Mexico and Utah, but shortly after exposure to daylight they become colorless. From the gem and mineral collection of the Smithsonian's National Museum of Natural History. |
