This chrome imperial topaz crystal has a beautiful & gemmy yellow orange color. While beautiful in natural lighting, these chrome topaz crystals have the unique characteristic of fluorescence and will fluoresce a beautiful pink color when viewed in a dark room under a long wave UV flashlight. The last photo is an example of a group of Zambian chrome topaz crystals (this particular piece is shown somewhere in this group shot) displayed under natural light and under a long wave uv lamp to show the fluorescence seen in this material. *Keep in mind, some crystals will have a stronger fluorescence than others. We consider this piece to be a Thumbnail sized Specimen (TN).
