Physical properties

Formation & geological history

Forms mainly in hydrothermal veins and carbonate-hosted deposits, commonly with quartz, calcite, and sulfide minerals. Fluorite deposits range from Paleozoic to recent geologic ages.

Uses & applications

Used industrially as a flux in steel and aluminum production and as a source of hydrofluoric acid; attractive transparent material is used for carvings, cabochons, and mineral collections.

Geological facts

Green fluorite color commonly results from trace impurities or radiation-related color centers. Its perfect cleavage makes it relatively easy to chip despite its vivid appearance.

Field identification & locations

Common localities include China, Mexico, Mongolia, England, Spain, and the United States. Identify it by cubic crystal habits, very soft surface, strong cleavage, and inability to scratch glass; this polished specimen’s identity is visual and not definitive.
