This slab of native copper comes from Michigan’s Upper Peninsula, a region famous for producing some of the highest-quality copper specimens in the world. The piece displays classic metallic luster, natural reddish-brown tones, and distinct growth patterns preserved within the copper mass. Michigan copper formed when hydrothermal fluids deposited pure native copper within basalt flows, creating impressive masses like this one. A substantial and visually striking example of Michigan’s rich mineral history.
