3D ModelNoAI

Locality: unknown

Size: 4 cm x 4 cm x 4 cm

Formula: CaF2

Description: A transparent to translucent, often blue or purple mineral, commonly found in crystalline cubes in veins and associated with lead, tin, and zinc ores; hardness is 4 on Mohs scale; the principal ore of fluorine. Also known as Derbyshire spar; fluor; fluorspar. Fluorite is the only common mineral with four directions of perfect cleavage. This perfect cleavage combined with the mineral’s isometric crystal structure frequently cause it to cleave into ‘perfect’ octahedrons as shown in this sample.
