Fluorite with Quartz and Pyrite

Two large intersecting, part cubic crystals of pale apple-green Fluorite are completely coated with a 3 mm deep crust of milky Quartz crystals.   Preferentially coating the Quartz are many tens of bright metallic Pyrite crystals of about 1 mm and modified cubic habit.  This most attractive specimen is from Wheal Mary Ann, Menheniot, Cornwall, England, a mine renowned for its wide variety of coloured Fluorite.  Some edges of the Fluorite crystals show delicate peppermint-green colour zones.  A great combination of species from Wheal Mary Ann.
