“This a historical piece from the Prof. E Wm. Heinrich Collection from the University of Michigan. I acquired it recently from Michael Basal in Michigan who in turn acquired it from AES museum in Houghton when they deaccesioned it. It comes with Prof. Heinrich label and it is numbered 13.1. The side and top of the specimen is layered with liberal sheets of gold. The entire side is almost covered in sheets of gold which are layered in between the layers of Schist. A fine and very rare specimen!”
