The name fluorite comes from the Latin fluere which means “to flow“. This name comes from the fact that fluorite melts easily. Fluorite is the natural crystalline form of calcium fluoride (CaF2). It is a transparent to translucent, glassy mineral. When pure fluorite is crystal clear, however, flourite can show many different colors depending on tiny amounts of other elements taking the place of the calcium in the molecular structure. Sometimes a single crystal may have bands of several colors. Fluorite often forms beautiful cube-shaped crystals. The hardness of fluorite is only 4 on mohs' scale, which means that it can be easily scratched with a knife. For this reason, fluorite is not commonly fashioned into gems, since it is not durable enough to maintain an unblemished polish with normal jewelry use. Fluorite is a popular lapidary material and is often fashioned into spheres, dishes, vases, carvings and other ornamental objects. In the past, Illinois was the largest supplier of Fluorite, world wide. It is still the state stone for Illinois, however, due to the high costs of mining, the mines were closed in 1995.
