Physical properties

Hardness: 4 on Mohs scale; Color: typically clear, purple, green, or yellow; Luster: Vitreous; Crystal Structure: Isometric (cubic); Cleavage: Perfect octahedral; Specific Gravity: 3.1

Formation & geological history

Formed through hydrothermal activity in veins where it often occurs alongside lead and zinc ores. It can be found in limestone cavities and igneous rock environments.

Uses & applications

Used in the manufacture of hydrofluoric acid, as a flux in steel making, and in the production of high-quality camera and telescope lenses. This specific specimen is a decorative carving for collectors.

Geological facts

Fluorite is the original mineral used to define the phenomenon of fluorescence; many specimens will glow blue or violet under UV light. It is often referred to as 'the most colorful mineral in the world'.

Field identification & locations

Identify by its vitreous luster, cubic crystal habit (if raw), and its relative softness (can be scratched by a knife but not a penny). It is found globally across China, Mexico, South Africa, and the USA.
