These beautiful, extra-grade (beautiful green/purple color, translucent, with <10% matrix) Fluorite Octahedron are cut by miners, who split the Fluorite along its natural cleave lines. Fluorite forms naturally in octahedron-shaped molecules and this is a beautiful example of the sacred geometry contained within crystals. 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. Some colours 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 octahedral faces can sometimes be 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.
Fluorite is one of the more famous fluorescent minerals. Many specimens strongly fluoresce, in a great variation of colour. In fact, the word "fluorescent" is derived from the mineral Fluorite. The name of the element fluorine is also derived from Fluorite, as Fluorite is by far the most common and well-known fluorine mineral.
