Fluorite is a mineral which is easily found in nature. It can be found in geodes or druses. In a pure state it is colourless and transparent, even though many times can have different colouring caused by organic or mineral impurities; usually purple, although it can also be blue, green, pink, orange or yellow. Many varieties are fluorescent. The crystalline varieties are used to carve vessels and other ornaments; the clorophane variety is the one used as a gemstone. It is also used in the manufacturing of high quality optical apparatus. It is a protective stone. It helps to distinguish when receiving external influences or manipulation attempts. It is highly effective against radiation. It is also the most appropriate crystal against any kind of disorganization.
