    • Great Rock Polisher for the price!
Style: Gemstone Mix
I purchased this for a Christmas Present for one of my granddaughters. I saw cheaper ones but opted for the heavier one and am glad I did. Works just like a more expensive one I have seen. The rocks came out perfect!!! I ordered extra sand and rocks and have found that it will give her many hours of activity with this rock polisher. When she comes to visit me I plan to help her make jewelry from some of her favorite rocks. ... show more

    • Not shiny

Review Image by Katelyn A. Katelyn A.
Our family enjoyed this entire process, ( truly, in these past hard months, it has been the only unity we have found, without arguing, so thank you!!) Unless we did something wrong, our stones never came out shiny.. they are still beautiful, but all are dull. I do feel we followed the instructions to the letter. Like I said either way, we love them, and it was fun! ... show more

    • 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.

    • Gift for grandson but he liked it and will do some here.
Style: Gemstone Mix
A bit noisy but that’s expected. It was exciting for an 11 - 12 year old grandchild to use with us on his visits. Next he’s going metal detecting in the pathways where Sherman’s army marched through his family land. You take advantage of what is locally available. Fortunately he lives in a very historical area. It’s great. ... show more
