A large and spectacular crystallized Michigan copper, from the Gillespie Mineral Museum in Florida by way of an odd peregrination! The big, fine, chunky crystals on this specimen measure to over 4 cm, with a beautiful sheen and sharp faces. Just a really impressive old Michigan piece! In person, it is even more 3-dimensional and dramatic. 12 x 11.5 x 4 cm
