fluorite
Cubic optical mineral
Fluorite is a mineral composed of calcium fluoride, typically forming cubic crystals in a range of colors—purple, green, blue, yellow, or colorless.
It's prized by mineral collectors for its vivid hues and geometric crystal structure.
Industrially, fluorite serves as a flux in steelmaking and a source of fluorine for chemical production.
The mineral often fluoresces under ultraviolet light—a phenomenon named after it.
