Fluorite

Fluorite also called fluorspar is the mineral form of calcium fluoride CaF 2 belongs to the halide minerals crystallizes in isometric cubic habit although octahedral and more complex isometric forms are not uncommon. The Mohs scale of mineral hardness based on scratch hardness comparison defines value 4 as Fluorite. Pure fluorite is transparent both in visible and ultraviolet
