Physical properties
Hardness of 4 on the Mohs scale, variable colors including purple, green, and yellow, vitreous luster, and perfect octahedral cleavage.
Formation & geological history
Forms in hydrothermal veins and carbonate cavities through the precipitation of fluorine-rich mineralizing solutions.
Uses & applications
Used in metallurgy as a flux, in the manufacture of optical lenses, and prized as a mineral specimen for collections.
Geological facts
Fluorite gives fluorescence its name, as many specimens glow strongly under ultraviolet light due to trace impurities.
Field identification & locations
Easily identified by its distinct cubic crystal habit and lower hardness that allows it to be scratched by a knife.
