  • Love this set!
Style: Gemstone Mix
Got a rock tumbler for Christmas and I love it! Had to get more grit and rocks and used the same brand as the tumbler and the rocks it comes with are really pretty and they turn out so well! Comes with instructions so it’s easy to follow. This makes a great gift for rock lovers.

  • Get more out of your rock tumbler
Style: Madagascar Mix
The rock selection is heavy on Rose Quartz. I liked that the kit has rocks with similar hardness so they can be successfully polished together. The sets of pre-measured grit make it easy to use the right amount for each step.
