A SUPERB Michigan toenail copper. An aesthetic, arborescent, flattened, vertical fan of hoppered tetragonal copper crystals with an excellent patina rests on a nest of spinel-twinned copper crystals. Hoppered tetragonal copper crystals of this habit and quality from the Copper Country are RARE. The back of the fan consists entirely of flattened, spinel-twinned copper crystals. Ex Sam Nasser Collection. 3.0 x 2.6 x 2.3 cm
