Cute Sunlight Rock Tumbler Educational DIY Stone Polisher Jewelry Maker Machine

Mother Nature polished that stone by gently washing it in water and sand or gravel until all the rough edges were smoothed away. Then the inner colors and unique composition of the stone were uncovered! You can do the same thing in your Rock Tumbler – It is faster than Nature, but still takes time and patience. Still, you can expect to have beautiful, polished stones in 2 to 4 weeks.
