Michigan Copper Country copper in calcite specimens are amongst the most desirable minerals species, along with superbly crystallized copper specimens, from this district. Here we have a large, very glassy, transparent to translucent, complete-all-around, double terminated calcite crystal heavily infused with native copper with a nice patina. This historic classic, probably dating prior to World War I, is in outstanding condition, with only very minor edge-wear. Specimens of this size and quality are only available from recycled collections. Ex. Mullane Collection accompanied by an old Burminco label with a May, 1952 date.
