Physical properties
Hardness of 4 on Mohs scale, variable colors including green and purple, vitreous luster, isometric crystal system, and perfect octahedral cleavage.
Formation & geological history
Forms in hydrothermal veins and sedimentary deposits through the precipitation of fluorine-bearing solutions, often associated with metallic ores.
Uses & applications
Widely used in metallurgy as a flux, in the manufacture of optical lenses, and as a popular decorative gemstone and collector specimen.
Geological facts
Fluorite exhibits strong fluorescence under ultraviolet light, a phenomenon named after the mineral itself.
Field identification & locations
Easily identified by its relatively low hardness and octahedral cleavage; commonly found worldwide, especially in China, Mexico, and the UK.
