Natural Copper Specimens
Natural Copper Specimens, from the Keweenaw copper deposits of Michigan, U.S.A.
They are generally decent size pieces of metal - they always weigh quite a lot, being made of metal. They're also surprisingly fragile, as the interesting bits are the small flakes coming off the sides of the main piece. They are very well packed for delivery, in soft materials to avoid damage. Copper is, of course, very malleable.
