Physical properties

Hardness: 4 on Mohs scale. Color: Pale pink to rose red. Luster: Vitreous (glassy). Crystal structure: Isometric/Cubic (often forming octahedral or cubic crystals). Cleavage: Perfect octahedral. Specific gravity: 3.175–3.184.

Formation & geological history

Formed through hydrothermal activity in veins where hot, mineral-rich fluids circulate through host rock. Pink varieties are often found in alpine-type fissures or high-altitude granite deposits and are particularly associated with the Hercynian orogeny era.

Uses & applications

Used primarily as a collector's specimen due to rarity. General fluorite is used as a flux in steelmaking, in the manufacture of hydrofluoric acid, and high-quality clear specimens are used in optical lenses.

Geological facts

Pink is one of the rarest colors for fluorite. The color is typically caused by color centers involving rare earth elements or exposure to natural radiation. The most famous 'pink fluorite' comes from the Alps near Chamonix, France, and Switzerland.

Field identification & locations

Identify in the field by its distinct octahedral cleavage (it breaks into triangles/diamonds), its relatively low hardness (can be scratched by a steel knife), and its habit of forming in clusters of small octahedral crystals. Look for it in high-altitude granitic regions or metallic ore veins.
