Physical properties

Translucent blue-green, glassy luster, cubic crystal habit; fluorite has Mohs hardness 4 and perfect octahedral cleavage. The image alone does not show enough detail for a confident identification.

Formation & geological history

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

Uses & applications

Used as a collector specimen and gemstone; industrial fluorite is an important source of fluorine and flux in metal smelting.

Geological facts

Fluorite commonly forms cubic crystals, though cleavage can produce octahedral fragments; its color varies widely.

Field identification & locations

The pointed, transparent blue-green form may be a natural crystal or a cut specimen. Confirm with hardness, cleavage, and mineral testing; common sources include China, Mexico, and the United States.
