Physical properties
Hardness of 4 on the Mohs scale, vitreous luster, isometric crystal system with perfect octahedral cleavage, and a specific gravity of 3.18.
Formation & geological history
Forms in hydrothermal veins and carbonate rocks through the precipitation of fluorine-rich solutions.
Uses & applications
Used in metallurgy as a flux, manufacturing hydrofluoric acid, optical lenses, and as a popular lapidary specimen.
Geological facts
Fluorite is the defining mineral for a hardness of 4 on the Mohs scale and often exhibits strong fluorescence under UV light.
Field identification & locations
Identified by its relatively low hardness and perfect cleavage; commonly sourced from China, Mexico, and South Africa.
