Michigan Copper Nuggets

Upper Michigan's Copper Country has the purest native copper in the world. Metal detectors are used to locate the copper chunks in the poor rock piles that were overlooked by the miners from many years ago. The chunks are then tumbled to remove the host rock (basalt) revealing the unique copper nugget shapes. RGI's copper nuggets are ALL NATURAL with no acid treatment and have not been melted - only tumbled and rinsed with water.
