Description
Consider what had to happen for this specimen to exist. Michigan’s Keweenaw Peninsula contains the world’s largest deposit of native copper — pure copper metal, not ore, occurring in basalt amygdales and conglomerate beds. It was mined by Indigenous peoples for thousands of years before European contact. Arborescent (‘tree-like’) specimens show copper’s natural tendency to branch as it grows from solution.
This specimen originates from Keweenaw Peninsula, Michigan, USA, one of the world’s most significant localities for this type of material. Collectors and scientists have drawn from this region for generations, and for good reason: the combination of geological conditions here produces specimens of exceptional quality and clarity.
Every specimen is unique. Photographs approximate the visual experience, but the real thing — its weight, its luster under a raking light, the way it catches the corner of your eye — can only be experienced directly.
