Fluorescent stones are minerals that emit visible light when exposed to ultraviolet (UV) light. This phenomenon occurs because certain minerals absorb UV radiation and then re-emit it as visible light, often in vibrant colors. Common examples of fluorescent stones include fluorite, calcite, and willemite. These stones are often used in geology and mineralogy to help identify specific minerals. Collectors and enthusiasts enjoy using UV lamps to reveal the hidden colors of these stones, making them popular in both educational settings and as decorative items. Fluorescent stones can be found in various locations around the world, each exhibiting unique fluorescence characteristics.
