Physical properties
Hardness: 4 on Mohs scale. Color: Varies from green, purple, pink to yellow. Luster: Vitreous. Crystal Structure: Isometric (cubic). Cleavage: Perfect octahedral cleavage.
Formation & geological history
Formed in hydrothermal veins and carbonate rocks, often associated with metallic ores like lead and zinc.
Uses & applications
Used in the manufacture of optical equipment, steel production, and as a popular mineral specimen for collectors.
Geological facts
Fluorite gives fluorescence under ultraviolet light, a property named after the mineral itself.
Field identification & locations
Identified by its distinctive lower hardness (scratched by a knife, does not scratch glass easily) and cubic crystal habit.
