Physical properties

Formation & geological history

Forms in hydrothermal veins, often associated with metallic ore deposits like lead and zinc, as well as in cavities of limestone and dolomite rocks.

Uses & applications

Used in mineral specimens, lapidary arts, jewelry, and industrially as a flux in steelmaking and the manufacturing of hydrofluoric acid.

Geological facts

Fluorite is the mineral definition of hardness 4 on the Mohs scale. It exhibits strong fluorescence under ultraviolet light, a phenomenon first named after the mineral itself.

Field identification & locations

Easily identified by its relatively low hardness (can be scratched by a knife or glass), octahedral cleavage, and characteristic glassy luster with vibrant colors. Commonly found in China, Mexico, South Africa, and the UK.
