Green fluorite (likely)

Fluorite, calcium fluoride (CaF₂)

AI-generated identification · may be incorrect

Pale green, translucent, and vitreous with apparent cubic cleavage and a blocky crystal form; Mohs hardness 4, specific gravity about 3.18. The rough, broken-looking surfaces and color are consistent with fluorite, though the photograph alone cannot exclude green calcite or glass.

Physical properties

Formation & geological history

Forms from hydrothermal fluids in veins and cavities, commonly with quartz, barite, and galena; deposits range from Paleozoic to modern geologic ages. Major sources include China, Mexico, England, the United States, and Namibia.

Uses & applications

Used as a flux in steel and aluminum production, as a source of hydrofluoric acid, and as a collector mineral; transparent varieties are cut as gemstones, though they are relatively soft.

Geological facts

Fluorite commonly fluoresces blue, purple, green, or cream under ultraviolet light, and its name derives from its use as a metallurgical flux.

Field identification & locations

Check for cubic cleavage, glassy luster, moderate heft, and hardness below steel; a knife may scratch it. Common specimen value is about $5–$30, while well-formed or strongly fluorescent pieces may sell for $50–$200+.
