Copper- large crude crystals with Silver
Calumet and Hecla Mine, Calumet, Houghton County
Michigan, United States
4.7 x 3.7 x 3 CM (miniature)
price: $250

An old specimen from Houghton County with sizable (2 CM) distinct yet crude crystals standing above a mostly Copper matrix. Some sharp faces are seen but overall the crystals are very distorted. A few spots of Native Silver are also seen with magnification.
