Physical properties
Hardness of 4 on the Mohs scale, vitreous to glass-like luster, isometric crystal system with perfect octahedral cleavage, pale to mint green color with characteristic cleavage planes and translucent appearance.
Formation & geological history
Forms primarily through hydrothermal processes in veins, often associated with metallic ores like lead and zinc, or in pegmatites and sedimentary rocks as a cavity filling.
Uses & applications
Used as a flux in steelmaking, in the production of hydrofluoric acid, high-performance optical lenses, lapidary carvings, decorative ornamental items, and crystal collecting.
Geological facts
Fluorite exhibits fluorescence, glowing under ultraviolet light. The physical phenomenon of fluorescence was actually named after this mineral.
Field identification & locations
Can be identified by its softness (easily scratched by a steel nail), cubic/octahedral cleavage surfaces, and vitreous luster. Commonly found in China, Mexico, South Africa, the UK, and the USA.
