Physical properties
Mohs hardness of 4, vitreous luster, cubic crystal system, perfect octahedral cleavage, and a specific gravity of 3.18. Colors vary widely including clear, purple, green, yellow, and blue.
Formation & geological history
Forms primarily in hydrothermal veins and carbonate host rocks through the precipitation of fluorine-bearing solutions at low to moderate temperatures.
Uses & applications
Used extensively in metallurgy as a flux, in the manufacturing of optical equipment, hydrofluoric acid production, and as a popular mineral specimen for collectors.
Geological facts
Fluorite exhibits strong fluorescence under ultraviolet light, a phenomenon first scientifically described and named after the mineral itself.
Field identification & locations
Identified easily by its characteristic cubic crystal habit, relatively soft Mohs hardness of 4, and perfect cleavage. Common localities include China, Mexico, South Africa, and the UK.
