Tumbled stones are smaller pieces of crystals or rocks that have been processed in a rock tumbler with water, sand, and grit. Over weeks in a tumbler, the stone edges and surfaces become smooth and sometimes highly polished to bring out the beauty of the stone. The pleasing shape and size of tumbled stones make them desirable as more inexpensive and usable crystals.
