An incredible copper specimen that would be impossible to distinguish from electrolytic copper, if not for the rock matrix and the fact that I know who collected it. A myriad copper crystal forms include flattened spinel twins and aborescent crystal groups. This piece comes from the famous Cliff fissure, source of many fine Copper Country specimens. 5.0 x 4.1 x 3.0 cm
