Physical properties
Mohs hardness of 4, exhibits vitreous luster, perfect octahedral cleavage, and ranges from pale mint to deep emerald green with isotropic optical properties.
Formation & geological history
Forms in hydrothermal veins and carbonate cavities through the precipitation of fluorine-rich solutions.
Uses & applications
Widely used in metallurgy as a flux, manufacturing of hydrofluoric acid, and popular in crystal healing and mineral collecting.
Geological facts
Fluorite gives fluorescence its name, as many specimens glow strongly under ultraviolet light due to impurities like yttrium.
Field identification & locations
Easily identified by its characteristic low hardness of 4 and octahedral crystal habit, commonly sourced from China, Mexico, and South Africa.
