A mesmerizing piece of Rainbow fluorite.

Fluorite is Allochromatic, meaning that it can be tinted with elemental impurities. It is one of the most varied colored minerals in the mineral kingdom, and the colors may be very intense and almost electric.



A crystal's colour is dictated by the way light interacts with the chemicals in it, and by how these are bonded in an orderly structure, or lattice. Any impurities that work their way into fluorite's lattice can alter its apparent colour. For example, manganese ions turn it orange.
