Physical properties
Mohs hardness of 4; vitreous luster; isometric crystal system with perfect octahedral cleavage; specific gravity around 3.18.
Formation & geological history
Forms primarily in hydrothermal veins and carbonate host rocks through low-temperature deposition from fluorine-rich solutions.
Uses & applications
Used in metallurgy as a flux, in the manufacturing of optical lenses, and as a popular collector mineral or gemstone.
Geological facts
Fluorite exhibits strong fluorescence under ultraviolet light, a property that derives its name from the mineral itself.
Field identification & locations
Easily identified by its relatively low hardness (can be scratched with a knife) and cubic or octahedral cleavage. Commonly found worldwide, though uncharacteristic for the coastal plain sedimentary deposits near the given coordinates.
