Physical properties
Typically translucent green with pale banding and vitreous luster; cubic crystal system with perfect octahedral cleavage. Mohs hardness 4; specific gravity about 3.18, though this polished/carved specimen has an artificially shaped hexagonal tower form.
Formation & geological history
Forms mainly in hydrothermal veins and cavities, often with quartz, calcite, and galena; deposits range from Paleozoic to younger ages. Common sources include China, Mexico, England, Morocco, and the United States.
Uses & applications
Used industrially as a flux in steel and aluminum production and as a source of hydrofluoric acid; attractive pieces are sold as décor and collector specimens. It is generally unsuitable for durable jewelry because of its softness and cleavage.
Geological facts
Green fluorite can show zoning, color bands, and occasional fluorescence under ultraviolet light. The image may also resemble green banded calcite, but the glassy translucence and geometry are more consistent with fluorite.
Field identification & locations
Identify by softness, perfect cleavage, cubic habit, and possible UV fluorescence; avoid scratches and thermal shock. Common market value is about $10–$40 for a small polished tower, or $50–$150+ for vivid, well-banded material.
