Gold

Gold in Quartz from the Holy Terror Mine at Keystone, South Dakota. Ex Rock Currier #9255. Few examples survive from this mine, a handful in private collections and the pieces in the School of Mines Geology Museum at Rapid City South Dakota. I was very happy to get this piece from the Rock Currier collection.
