Physical properties

Hardness of 4 on Mohs scale, green color, vitreous luster, isometric crystal system, perfect octahedral cleavage, specific gravity of 3.18.

Formation & geological history

Forms in hydrothermal veins and sedimentary deposits, often precipitated from fluorine-rich solutions within rock cavities.

Uses & applications

Used in decorative crystal spheres, jewelry, and as a flux in steel and aluminum manufacturing.

Geological facts

Fluorite exhibits strong fluorescence under ultraviolet light and gives the phenomenon its name.
