Pyrite and Magnetite     French Creek Mines, St. Peters, Chester Co., PA.    Ex. Dr. Steve Chamberlain Collection.  This crystal cluster measures 3.5 x 2.6 x 1.5 cm and is an outstanding example from this classic locality.  It displays well looking far larger than it actually is.  The luster is nice, zero damage and an interesting, attractive frouping of cubic crystals.  Only minor magnetite on base (or back) of specimen.  Some attached Styrofoam.  This is a classic east coast locality which is known for its pyrites and one can see why when viewing this fine example.  100$
