2nds/Discounted: This piece of copper ore slab has been discounted because the coating of resin polish extends out around the base of the piece by an extra 3 millimeters. 

Beautiful specimens of copper ore pieces with quartz, epidote, and basalt. Discovered in Michigan's Keweenaw Peninsula, these interesting rock formations occur with native copper in veins, spots, streaks, or large masses mixed with the rock matrix. 

One side is raw, and the other is polished and coated to enhance the beauty of the piece. Each one is unique! Yours will be intuitively hand-selected for you.
