Physical properties
Mohs hardness of 4; vitreous luster; isometric crystal system with cubic habits; distinct octahedral cleavage; specific gravity around 3.18.
Formation & geological history
Formed in hydrothermal veins and sedimentary deposits via mineral-rich fluids precipitating at low to moderate temperatures.
Uses & applications
Used in metallurgy as a flux, manufacturing hydrofluoric acid, optical lenses, and prized as a mineral specimen in collections.
Geological facts
Fluorite exhibits strong fluorescence under ultraviolet light, a phenomenon named after the mineral itself.
Field identification & locations
Identified by its lower hardness (scratched by glass), cubic crystal forms, and characteristic green coloration; found globally, notably in China, Mexico, and the USA.
