When the lights go out, some rocks put on a show. Under the glow of a black light, these minerals emit a vibrant array of colors, creating a mesmerizing spectacle. This phenomenon, known as fluorescence, occurs when ultraviolet light excites electrons within the rock’s crystal structure, causing them to release energy in the form of visible light.
5 Popular Fluorescent Rocks
1. Calcite
* Color: White, orange, pink, blue, green
* Occurs in various geological formations, including caves and mines
* Fluorescence: Blue, green, white
2. Fluorite
