Though fluorite plays only a minor role on it - I like that one!

Nice one, beautiful colour zoning/phantoms inside the crystals!
Thanks Tobi.
I would like to know more about this locality. From what I have seen, it produces fluorite in a variety of colors. Most of the pieces I have seen feature well-defined phantoms or at least strong color zoning.
