Pale green tumbled stone, possibly fluorite

Uncertain from the photo; appearance is consistent with fluorite (CaF₂)

AI-generated identification · may be incorrect

Translucent pale yellow-green with a vitreous to slightly waxy surface and irregular, rounded shape. If fluorite, hardness is 4 Mohs and crystals are cubic with perfect octahedral cleavage; the image alone cannot confirm the identification.

Physical properties

Formation & geological history

Fluorite commonly crystallizes from mineral-rich hydrothermal fluids in veins and cavities, across many geological ages. This piece appears tumbled or naturally rounded; its exact origin is not determinable visually.

Uses & applications

Fluorite is used as an industrial flux and source of fluorine, and as a decorative or collectible stone; softer pieces are less suited to everyday jewelry.

Geological facts

Fluorite often fluoresces under ultraviolet light, though not all specimens do.

Field identification & locations

The translucent color and rounded edges fit tumbled fluorite, but similar-looking minerals and glass can be confused with it. Check hardness and cleavage, or use mineral testing for confirmation; fluorite occurs worldwide in hydrothermal deposits.
