The Champion 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 a fine native copper crystal group for the locale, with elegant branching form and a nice rich chocolate-brown patina. An American mineral classic from the Proctor Family Trust Collection.
