Native Copper

Veins of native copper run like lightning through ancient basalt and calcite in this striking specimen from Michigan’s historic Ontonagon region. The polished surface reveals exceptional textural nuance—intricate oxidation patterns and a warm copper glow set against a backdrop of darker matrix and pale mineral seams. A vivid expression of geological contrast from one of North America’s most storied copper belts.
