Polished river rocks are smaller river rocks that have been tumbled in a rock tumbler with a series of increasingly finer grades of polishing powder until they reach a glossy finish. Some of the more plentiful pebble beaches are along the coast of the Pacific Ocean, beginning in Canada and extending down to the tip of South America in Argentina.
