M250 Copper

M250 Copper


Here is a nice specimen of natural Copper from Keweenaw Peninsula, Michigan. This is natural native copper which has been mostly removed from the matrix rock which was surrounding it.  It is the natural formation just as it formed in the rock.  It measures 3 1/4″ x 3 1/8″ x 1″ thick. Very nice.
