Physical properties
Mohs hardness of 4, vitreous luster, isometric crystal system, perfect octahedral cleavage, and variable colors including green, purple, and blue.
Formation & geological history
Formed in hydrothermal veins and sedimentary deposits through the precipitation of fluorine-bearing solutions.
Uses & applications
Used widely in metallurgy as a flux, in the manufacture of optical lenses, and as a popular collector mineral and carving material.
Geological facts
Fluorite is the defining mineral for a hardness of 4 on the Mohs scale and often exhibits strong fluorescence under ultraviolet light.
