Collect various kinds of rocks and whet them into beautiful polished stones using the Rock Tumbler. Part art, part science, this rotary tumbler allows you to use four grades of grinding powder to achieve the perfect polish. Experiment with different types of stones and rocks under different tumbling conditions, the results may surprise you. Use the contents in the kit or collect your own rocks to turn into gemstones.
Nature polishes stones by gently washing them in water and sand or gravel until all the rough edges are smoothed away. Then the beautiful colours and composition of the stone are uncovered. The Rock Tumbler does the same thing; with the tumbling action and grit smoothing off the sharp points and edges but speeds up the process creating stunning, polished stones in 2–4 weeks.
