| From the Nayal Black Hawk Mine, near Castle Dome, Arizona, this piece has a large Fluorite crystal in the middle, surrounded by smaller crystals on either side. The Fluorite glows violet while some Willemite glows creamy yellow. Also on the left but difficult to see in the picture is some green Hyalite, some of which occurs inside the Fluorite crystals, resulting in a slight halo effect. Shown under shortwave UV. Dimensions are 3 x 1 1/2 x 1 inches. Price: $20 |
