Physical properties
Hardness of 4 on the Mohs scale, variable colors including purple and green, vitreous luster, isometric crystal system, and perfect octahedral cleavage.
Formation & geological history
Formed mainly in hydrothermal veins and carbonate host rocks through precipitation from mineral-rich aqueous solutions.
Uses & applications
Widely used in metallurgy as a flux, in the manufacture of optical equipment, and as a popular mineral specimen for collectors.
Geological facts
Fluorite exhibits strong fluorescence under ultraviolet light, a phenomenon that derives its name from this mineral.
Field identification & locations
Identified easily by its characteristic cubic crystals, relatively low hardness, and perfect cleavage. Found globally, notably in China, Mexico, and the United States.
