Mineral Classification

Minerals, such as gypsum, when illuminated with ultraviolet (UV) light, X-rays, and/or electron beams appear to glow in vibrant colors that are not present when the mineral is viewed with regular light. For example, calcite that looks white in visible light can fluoresce in a variety of colors such as red, blue, pink, green, and orange. The ...Web
