Physical properties
Hardness of 4 on the Mohs scale, variable colors including purple, green, and blue, vitreous luster, and cubic crystal system with perfect octahedral cleavage.
Formation & geological history
Forms in hydrothermal veins and as a replacement deposit in limestone, created by precipitation from fluorine-bearing solutions.
Uses & applications
Used in metallurgy as a flux, in the manufacturing of optical equipment and hydrofluoric acid, and as a popular mineral specimen.
Geological facts
Fluorite is the defining mineral for a hardness of 4 on the Mohs scale and exhibits strong fluorescence under ultraviolet light.
Field identification & locations
Identified by its characteristic cubic crystals, lower hardness than quartz, and perfect cleavage; commonly sourced from China, Mexico, and the USA.
