Natural Keweenaw Copper Specimens
Natural Keweenaw Copper Specimens, from Michigan in the United States of America.
They are generally decent size pieces of metal; we sell 40MM, 50MM and 75MM pieces, although obviously there is a wide variance in natural pieces.
These pieces 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.
