Buying Polished petoskey stone

buying This stone was picked off the beach in Petoskey and given a good polish. Dimensions are approximately 2.4” x 3.8 ” x 1.5” . This stone has a nice front side that took a great polish. Backside of the stone was much rougher with less pattern so we left it natural. We did some grinding on the bottom of the stone so that it can stand upright. We polish all of our stones using polishing wheels, we do not spray them or coat them in anything.
