Silver and Copper
stock #LH-702
Calumet
Michigan, United States
6.7 x 3.1 x 1.7 CM (cabinet)
price: $120
Spring 2020

A hackly mass of Copper holds some areas of crudely crystalline Silver. The largest zone of Silver also has a few areas of Copper growing on the Ag which is less common than the other way round. A good mixed native element specimen from the Hitchings collection that he obtained in 1970. This sort of association is unique to the upper Pennisula of Michigan.
