Physical properties
Hardness of 4 on the Mohs scale, exhibits vibrant color zoning including green, purple, and clear hues, vitreous luster, isometric crystal system, perfect octahedral cleavage, specific gravity of 3.18.
Formation & geological history
Forms in hydrothermal veins, often associated with metallic ores like lead and zinc, as well as in cavities of sedimentary and igneous rocks.
Uses & applications
Commonly used in jewelry and lapidary arts, as a flux in steelmaking and metal smelting, and in the manufacture of specialized lenses for optics.
Geological facts
Fluorite gives fluorescence its name, as many specimens glow strongly under ultraviolet light due to trace impurities.
Field identification & locations
Identified by its relatively low hardness of 4 (can be scratched easily with a knife) and multiple cleavage directions; found globally with notable deposits in China, Mexico, and South Africa.
