Physical properties
Hardness of 4 on the Mohs scale, yellow to golden-brown color, vitreous luster, isometric (cubic) crystal system, perfect octahedral cleavage, and a specific gravity of around 3.18.
Formation & geological history
Forms primarily in hydrothermal veins and carbonate rocks, precipitating from mineral-rich solutions at varying temperatures.
Uses & applications
Used in metallurgy as a flux, in the manufacturing of certain types of glass and enamel, and highly sought after by mineral collectors and lapidary artists.
Geological facts
Fluorite gives the phenomenon of 'fluorescence' its name, as many specimens glow strongly under ultraviolet light due to trace impurities.
Field identification & locations
Identified by its relatively low hardness (can be scratched with a knife), cubic crystal habit, and perfect octahedral cleavage. Common localities include China, Mexico, South Africa, and the UK.
