GeoPicture of the week: Baryte on fluorite

What you are looking at is a picture of a baryte crystal growing on fluorite; the two minerals have not been cut or polished in any way, it is just the way they naturally are. Fluorite (or fluorspar) is a mineral made out of Calcium and Fluorine while Baryte is literally barium sulfate. It has an orthorombic, cubical symmetry. Absolutely stunning!
