I have never seen a silver/copper combo specimen quite like this. I have seen halfbreeds, and I have seen sharp silver on lumpy copper and vice versa, but not a sharply crystallized silver cluster WITHIN copper that is also sharply crystallized. In person, this piece is more 3-dimensional and it is simply exquisite. In person, there is relief between every silver crystal you see, and the backdrop of crystalized copper. It is mesmerizing. An exchange out of the collection of the Seaman Museum, the USA's finest repository of copper country specimens...but more notably also from their core collection, seldom traded or deaccessioned: that of mine captain John Reeder. Competition quality, at every level. Ex. Seaman Mineralogical Museum (John T. Reeder Collection)
