The Centennial mine, located in the Michigan's Keweenaw Peninsula copper district, is known for superb "herringbone" copper crystal groups, showing complex spinel-law twinning and fascinating crystal morphology. This is an exceptional native copper crystal group for the locale, with elegant branching form and a nice rich chocolate-brown patina. The crystal quality and aesthetics are really stunning on this piece, and it's appeal to collectors of aesthetic minerals is much broader than typical for a native copper specimen. An American mineral classic from the Proctor Family Trust Collection.
