A striking, feather-like, large cabinet copper specimen from Michigan's Copper Country and the Richard Hauck Collection. This outstanding, old-time specimen is extensively and sharply crystallized on both sides and has a beautiful, buttery, copper patina. The upper portion of this giant is very nicely arborescent. Copper crystal forms include spinel-twins and tetrahexahedrons. The scattered bit of embedded matrix and the two copper "feet" add character.
