Cabinet, 12.2 x 5.6 x 4.0 cm
Champion Mine, Painesdale, Houghton Co., Michigan, USA
Ex. Robert Nowakowski
A complete floater, this copper specimen looks like a growing bush or tree with the top much wider than the base. The whole specimen is composed of spinel twins of copper, elongated and graceful, to 6.7 cm in length. The patina color is a rich brownish-red (untouched by acidizing) with the brighter red possibly being a coating of cuprite.Another fine sculptural copper from this classic mine. Like others here, it has immediately recognizable, complex form that is very distinct in the mineral world from other coppers. This piece is a robust, complete-all-around display quality
