The Original Rock Tumbler™

Item# RM-TUMBLER

This classic rock tumbler kit polishes rough rocks to produce attractive gem-like stones, perfect for making your own jewelry. The electrically operated 110-volt rock tumbler does all the work in polishing about 8 ounces of rock per batch. Just add rough stones and the polishing grit to get started.

The entire rock polishing process takes about 3-4 weeks and uses two grades of grit plus a final polish. This kit comes with enough grit to polish a 1/2-pound batch of rocks; a refill is available.

The Original Rock Tumbler™

  • Two grades of polishing grit (0.63 oz coarse and 1.02 oz medium grit), and 0.81 oz of finishing polish
  • Glue and jewelry/keychain mounting hardware: make necklaces, pins, earrings, and charms
  • Rock tumbling instructions
  • Tumbler capacity is about 8 ounces (1/2 lb.)

Super product Review by
I bought this for my very energetic 6 year old son, who initially thought rocks would magically pop out polished in mere minutes. To my surprise, he waited patiently throughout the whole process, counting down days with increasing excitement. The fact that the resulting polished rocks emerged significantly smaller than they originally entered the tumbler did not phase anyone. "They are so beautiful," he exclaimed, and he immediately made a pendant out of one and a ring out of another to wear to school (where they were a huge hit). Now, my son is wishing to experiment with different types of rocks, and different types of gritty materials to see what the effects are. Wonderful intellectual growth activity!
Rock Tumbler problems Review by
I bought this for my grandchildren, but was disappointed to find that it had to be left on for weeks (electrical costs a consideration) and will require relatively expensive grades of 'grit' to produce a product. Would choose another product next time for my grandchildren.
Wonderful product! Review by
I let mine run on the coarse grind longer than indicated in the instructions (about a week). I just sort of left it in the garage and checked on it today. The rocks, which were hideously plain to start with, were already smooth and beautiful. So, I started a new cycle with the medium grit. Yes, it is noisy, but we keep it in the garage. I am definitely going to buy more rocks/grit and extra grit for smoothing rocks we find locally. I am perfectly pleased with this product!
Fast delivery, good quality Review by
We ordered this for our 10yo grandson who is our little scientist and picks up rocks from every outing. The tumbler looks great and we think it will only add to his interest in his rocks. We're very happy with the promptness of delivery and all looks to be in great shape. Glad you sent along a catalog, have a feeling there will be many more science interests stimulated for this young man, glad to have found this site with real working tools for young people.
