Green fluorite (likely polished/cut specimen)

Fluorite, calcium fluoride (CaF₂)

AI-generated identification · may be incorrect

Vivid green, translucent-to-transparent material with vitreous luster and prominent cubic cleavage; Mohs hardness 4, cubic crystal system, specific gravity about 3.18. The angular form and internal color zoning are consistent with fluorite, though dyed glass or resin cannot be excluded from the image alone.

Physical properties

Formation & geological history

Forms mainly in hydrothermal veins and carbonate-hosted deposits, commonly with quartz, calcite, and metallic sulfides. Deposits range from Paleozoic to younger geological ages.

Uses & applications

Used industrially as a flux in steel and aluminum production and as a source of hydrofluoric acid; attractive transparent pieces are collected or cut as ornamental gemstones.

Geological facts

Green fluorite commonly fluoresces blue, violet, or green under ultraviolet light. It is relatively soft and cleaves easily, making it vulnerable to scratching and breakage.

Field identification & locations

Common localities include China, Mexico, the United Kingdom, the United States, and Spain. Check for cubic cleavage, glassy luster, softness, and UV fluorescence; a hardness and refractive-index test can distinguish it from glass.
