Native Copper 2
Native copper nuggets.

Our primary offerings are:

Natural Native Tumbled Copper Nuggets:

These nuggets are available in any size range from 1/4” up to 6”+. Nuggets are sold on a per-pound basis, or per-flat basis (for smaller nuggets).

Tumbled native copper nuggets from Michigan's Upper Peninsula. This area known as the "Copper Country" or the "Keweenaw Peninsula" is known world wide for it's extremely pure and unique copper specimens.

Great for resale or use for jewelry making, medical uses, metaphysical properties, decorative pieces, educational and many others.

There are no purer natural native copper nuggets available anywhere. These have been tumbled and sorted by size. All are 100% pure native natural copper. Nothing ever from smelters or other sources! The copper has never been heated, melted or cast. These nuggets do sometimes contain some host rock as can be seen in the pictures.The pictures show average random samplings.

I tumble and sort these nuggets and sell them on a retail and wholesale basis. If you need large quantities contact me and I can help! I sell to many retailers who re-sell these at various shows, stores, even Ebay!
