Physical properties
Likely a small, translucent pale-green crystal with a vitreous luster and cubic cleavage; hardness 4 on the Mohs scale, cubic crystal system, specific gravity about 3.2. The photo alone cannot confirm the identification.
Formation & geological history
Fluorite commonly crystallizes from hydrothermal fluids in veins and cavities, often alongside quartz, calcite, or sulfide ores. Deposits occur in rocks of many ages.
Uses & applications
Used as an industrial flux, a source of fluorine, and as ornamental or collectible material; its softness limits jewelry use.
Geological facts
Fluorite often fluoresces under ultraviolet light, a property named after the mineral.
Field identification & locations
Check for distinctive octahedral cleavage and hardness near 4; common localities include China, Mexico, and the United States. A single small specimen like this is typically worth about $1–$10, depending on clarity and crystal quality.
