Michigan’s Champion mine is famous for it’s world-class crystallized copper specimens composed of tightly “woven” networks of “herringbone” spinel-twinned copper crystals. This is a fine cabinet-size specimen composed of elegantly-branching spinel twinned copper crystals with an unusual silvery patina. A great large Champion mine copper with superb crystallization, and good crystals on numerous sides. These are becoming fairly rare on the market. Ex. Ernie Schlichter Collection. Mark Cross photo.
