Large Cabinet, 21.5 x 20.5 x 18.5 cm
White Pine Mine, White Pine, Ontonagon Co., Michigan, USA

A huge, 8.7-pound specimen of native copper from classic Michigan copper country - extracted and left as-is! This is a very thick vein in the shape of two wings. You can see the matrix rock embedded with the copper. It has penny-bright luster that is actually a lot prettier and better in person.
