Fluorite, also known as fluorite, has a chemical composition of CaF2, and its crystal belongs to an equiaxed halide mineral. It emits blue or purple fluorescence under ultraviolet rays, cathode rays or heating, hence the name. Crystals are often cubes, octahedrons or cubes with twins, and the aggregate is granular or massive. Light green, light purple or colorless and transparent, sometimes with rose red and white stripes, with glass luster, transparent to opaque. Octahedral cleavage is complete. Mohs hardness 4, specific gravity 3. 18.

Colors are divided into: green fluorite, purple fluorite, blue fluorite, yellow fluorite and colorless fluorite. ?
