Copper
A very nice branching copper with nicely defined spinel twins from the Isle Royal No. 3 Mine. Specimens from this locality are not often seen and the area is now a National Park and collecting is not allowed. This is a very high quality specimen from this particular locality. A fantastic specimen for the avid Michigan copper collector. Specimen comes with custom acrylic base.
