Both halves of one of the very interesting nodules found in the copper mines of the Keweenaw Peninsula. Greyish on the fringes, reddish in the middle portion. If this nodule was not sawn it would be about 3.5cm thick. As it is, it has been cut in half and beautifully polished. Excellent example! And beautiful, too!
