Physical properties

Hardness of 4 on the Mohs scale, variable colors including purple, green, and clear, vitreous luster, and isometric crystal system with cubic habits.

Formation & geological history

Forms in hydrothermal veins and carbonate rock cavities through low-temperature precipitation from mineral-rich aqueous solutions.

Uses & applications

Widely used in metallurgy as a flux, in the manufacture of optical lenses, and as a popular mineral specimen for collectors.

Geological facts

Fluorite exhibits strong fluorescence under ultraviolet light, a phenomenon named after the mineral itself.

Field identification & locations

Identified by its characteristic cubic crystal form and lower hardness compared to quartz; commonly found in worldwide localities like China, Mexico, and England.
