Native Copper from Calumet Michigan

Native copper is an uncombined form of copper that occurs as a natural mineral. Copper is one of the few metallic elements to occur in native form, although it most commonly occurs in oxidized states and mixed with other elements. This piece is from the Red Jacket Shaft mine and was found at a depth of 9,000 feet. It’s still just as it was found, approximately 4 inches in length and a beautiful addition to your collection.
