Fluorite is chemically calcium fluoride, and is a common mineral that often forms cubic crystals in hydrothermal veins. It can come in an extremely wide variety of colours such as blue (typical of this locale), green, pink, lilac, colourless etc. As it is soft and easily scratched (Mohs hardness 4), care should be taken when storing and handling fluorite so that it doesn’t abrade against harder stones and other objects.
