Why do scheelight glow?

She light, or "scheelite," glows due to its fluorescence properties. When exposed to ultraviolet (UV) light, scheelite emits visible light, typically a bright blue or white glow. This phenomenon occurs because the mineral contains tungsten, which absorbs UV radiation and re-emits it as visible light. The glow can be observed in various geological contexts, making scheelite an interesting specimen for collectors and geologists.
