Green fluorite (likely)

Fluorite, CaF₂

AI-generated identification · may be incorrect

Pale green, translucent to transparent with a vitreous luster and prominent cleavage; hardness 4 on the Mohs scale, cubic crystal system, specific gravity about 3.2. The rough, irregular piece is not diagnostic enough to confirm the identification from the image alone.

Physical properties

Formation & geological history

Fluorite commonly crystallizes from hydrothermal fluids in veins and cavities, often alongside quartz or calcite; deposits range from ancient to geologically recent.

Uses & applications

Used as a source of fluorine in chemical and metallurgical industries; transparent, colorful specimens are collected and occasionally cut as gemstones, though fluorite is relatively soft.

Geological facts

Fluorite is famously fluorescent under ultraviolet light, a property named after the mineral.

Field identification & locations

Look for its glassy appearance and distinctive octahedral cleavage; common deposits occur in China, Mexico, South Africa, and the United States. A simple scratch test can help distinguish it, but avoid damaging a potentially valuable specimen.
