Physical properties
Hardness of 4 on the Mohs scale, typically light green or purple, vitreous luster, and isometric crystal system with perfect octahedral cleavage.
Formation & geological history
Forms in hydrothermal veins and sedimentary deposits through low-temperature precipitation from fluorine-bearing solutions.
Uses & applications
Used in metallurgy as a flux, in the manufacturing of optical equipment, and as a popular collector mineral.
Geological facts
Fluorite gives the phenomenon of fluorescence its name, as many specimens glow strongly under ultraviolet light.
Field identification & locations
Easily identified in the field by its distinct cubic crystal habit and relatively low hardness compared to quartz.
