USA110 - Native Copper - Keeweenaw Peninsula, Lake Superior, Michigan, USA

Exceptional small specimen of crystallized copper from Michigan. The copper is finely crystallized in dodecahedrons to 1 cm. I also believe there are some tetrahexahedral faces present as well, but I am somewhat crystallographically challenged! From Herb Obodda. 4.3 x 3.2 x 2.1 cm.
