Fluorite is a very popular mineral, and it naturally occurs in all colours of the spectrum. It is one of the most varied coloured minerals in the mineral kingdom, and the colours may be very intense and almost electric. Pure Fluorite is colourless; the colour variations are caused by various impurities are deeply coloured, and are especially pretty in large well-formed crystals, which Fluorite often forms. Sometimes colouring is caused by hydrocarbons which can be removed from a specimen by heating. Some dealers may apply oil treatment upon amateur Fluorite specimens to enhance luster.
Fluorite has interesting cleavage habits. The perfect cleavage parallel to the faces can sometimes be octahedral peeled off to smooth out a crystal into a perfect octahedron Many crystals, especially larger ones, have their edges or sections chipped off because of the cleavage.
