Collection: Fluorite

Fluorite , also called fluorspar or fluorite , is a mineral composed primarily of calcium fluoride (CaF₂) . It is known for its wide variety of colors and its fluorescence under ultraviolet light.

🔍 Main Features

• Chemical formula: CaF₂

• Crystal system: Cubic (isometric)

• Hardness (Mohs scale): 4

• Density: Approx. 3.0 to 3.2 g/cm³

• Cleavage: Perfect, octahedral

• Colors: Violet, green, blue, yellow, colorless, pink, red, brown — highly variable depending on impurities

💡 Remarkable properties

• Fluorescence: Many fluorite crystals glow under UV light. This is where the word fluorescence comes from.

• Transparency: Transparent to translucent

• Use in optics: Pure fluorite is used to make lenses and prisms because it has low light dispersion (useful in astronomy or photography).

🏭 Industrial uses

1. Metallurgy: Flux to lower the melting point in the production of steel and aluminum.

2. Chemical industry: Source of fluorine to make hydrofluoric acid, refrigerants (such as CFCs), fluoropolymers (such as Teflon).

3. Gem and Collectible: Crystals sought after for their beauty and colors. Used as a semi-precious stone.
