1.Size:4 Grit Assortment


  • 【 Amount of Grit】This is a large amount of each size grit for the price. This kit comes with enough grit to complete approximately 16-20 lbs of rocks. This kit contains 1 lbs 60 Coarse Silicon Carbide Grit, 1 lbs 220 Medium Silicon Carbide Grit, 0.5 lb. 500 Fine Silicone Carbide Grit, 0.5 lb. 1200 Aluminum Oxide Final Polish Grit. COMPATIBLE WITH ALL BRAND TUMBLERS.
  • 【4 Steps】Be Patient. There are 4 total cycles, 7 days each to have pretty rocks / gems. Step 1, 60 Coarse Silicon Carbide Grit. Step 2, 220 Medium Silicon Carbide Grit. Step 3, 500 Fine Silicone Carbide Grit. Step 4, 1200 Aluminum Oxide Grit. Just measure in the grit, add enough water to cover the stones, seal the barrel, and tumble. The only variable is how much of the product to use in your rock tumbler. We suggest 2 tbsp of grit per pound of stones, which is a good rule of thumb.
  • 【Jars, Labels & a Scoop】Nice hard plastic jars with lids (as opposed to plastic bags). Bottle caps are very secure. Definitely they will not leak. Use the amount you need and set it back on the shelf for the next round. A scoop is included for the correct dose. No need to pour the material out, which possibly make a mess while doing so. They are neatly packaged and easy to read labels. Tip: you could put your tumbler on a foam pad to eliminate noise.
  • 【Professional Material】The final polish in this kit is aluminum oxide which is what the professional use (as opposed to silicon carbide), making sure that you can achieve a wet polished look. If you are expecting nice shiny stones you will have to run the last stage. The aluminum oxide is what really makes them shine (providing you have done everything else correctly).
  • If you don’t get the satisfactory polished stones or there is anything else you are dissatisfied with, please contact us by E-mail, and within 24 hours,


This grit is perfect for use with rock tumblers of any brand!

Very happy with the ease of not only finding this product from the comfort of home, but how inexpensive it was, and it arrived to my home within days. Definitely a good quality product, with easy to use step by step order formation. A purchase I will certainly be making again.

The set includes a spoon. Did not notice until I started stage 3 (where the spoon was located)

The spoon was located in one of the bottles kind of buried in the media, wish the mouths of the containers were a little bit bigger, seems to work well.

The first 3 grits worked well, but the polish was not great. Ended up ordering 18,000 grit from a local rock shop. The rest works good though and a good place to start.

First three grits work as expected and make a good slurry. The 4th step basically turns to cloudy water and no polish after several weeks of tumbling and a borax wash before hand.Will not purchase again
