Malachite and Cuprite (ex Rich Kosnar and Pat Gross Collections)

Item Description

I have only seen a handful of Cuprite and Malachite specimens from this locality, and this micro piece is a great reference specimen for any Franklin collector or Malachite/Cuprite collector. I have photographed the crystals under the microscope as the piece is small, but both species are there to be sure. A great specimen from the famous Rich Kosnar collection, who obtained it from noted New Jersey collector, Pat Gross. The piece still resides in Pat's original hand-written, black plastic mounting box.
