Physical properties
Mohs hardness of 4, vitreous luster, cubic crystal system, perfect octahedral cleavage, and specific gravity around 3.18.
Formation & geological history
Formed in hydrothermal veins and sedimentary deposits through the precipitation of fluorine-bearing solutions, typically during high-temperature magmatic activity.
Uses & applications
Extensively used in metallurgy as a flux, in the manufacture of optical lenses, and as a popular specimen for mineral collectors.
Geological facts
Fluorite is famous for exhibiting strong fluorescence under ultraviolet light, a phenomenon named after the mineral itself.
Field identification & locations
Easily identified by its distinctive cubic crystal habit and relatively low hardness of 4, commonly mined in China, Mexico, and the USA.
