-Sorry but we are currently out of copper nuggets until fall-

Upper Michigan's Copper Country has the purest native copper in the world. Metal detectors are used to locate the copper that was missed by the miners from many years ago, then tumbled to remove the host rock revealing the unique nugget shape. The nuggets are ALL NATURAL with no acid treatment and have not been melted - only tumbled and rinsed with water.
Please note that very small amounts of host rock may remain on some of the nuggets and they are sold by weight - not volume.
