Physical properties
Hardness of 4 on the Mohs scale, typically pale to emerald green, vitreous luster, isometric crystal system, and perfect octahedral cleavage.
Formation & geological history
Forms in hydrothermal veins and carbonate cavities through the precipitation of fluorine-rich solutions.
Uses & applications
Used in metallurgy as a flux, manufacturing hydrofluoric acid, optical lenses, and as a popular mineral specimen for collectors.
Geological facts
Fluorite exhibits strong fluorescence under ultraviolet light and is the mineral defining hardness 4 on the Mohs scale.
Field identification & locations
Easily identified by its relatively soft nature, octahedral cleavage, and lower hardness than quartz. Common localities include China, Mexico, and South Africa.
