A crystal group of cubic, gemmy, golden fluorite which have a gentle coating of brassy colored marcasite to create a very attractive two-tone appearance. The underside of the specimen features beautiful white "saddle"-shaped crystals of dolomite. It's not common to have this much marcasite coating the fluorites like this. Usually we only see a few small inclusions in the crystals from Moscona. The largest fluorite measures 4 mm on edge. Ex Brian Kosnar Collection.
