Physical properties
Hardness: 4 (Mohs scale), Color: Mint to pale green with subtle banding, Luster: Vitreous, Crystal structure: Isometric (cubic), Cleavage: Perfect octahedral, Specific gravity: 3.18
Formation & geological history
Forms in hydrothermal veins where cooling fluids rich in calcium and fluorine precipitate crystals. This specimen has been carved and polished into a mushroom shape.
Uses & applications
Used primarily for metaphysical purposes, home decoration, and collection. In industry, fluorite is used as a flux for steelmaking and in the production of hydrofluoric acid.
Geological facts
Fluorite is the origin of the word 'fluorescence' because many specimens glow under UV light. It is often referred to as 'the most colorful mineral in the world.'
Field identification & locations
Identify by its relatively low hardness (can be scratched by a knife but not a penny) and its distinct cubic cleavage. Common in Mexico, China, and South Africa.
