Rock Tumbler Grit for 3 Pound Tumbler by RTumbler Professional Grade Rock Polishing Grit

I could not be happier with this product!! My son had gotten a national geographic tumbler and 1lb gemstone and grit for his birthday. It was fun, he enjoyed it but the stones never got that glossy finish. He's been an avid stone/gemstone collected for some time. So I got him this for Christmas so he could polish new stones. Wow! It's amazing. There's enough for 3 rounds easily, and the transformation in the stones is incredible! I didn't take before pictures but I wish I did. I will update with pictures on the next round of stones. I will DEFINITELY repurchase when we run out.

Works better than beginner stuff I had. Need to get more in larger size. But so far on number 2 and the rocks are looking good!

Work good just need bigger tumbler

I got a “S.T.E.M. Rock Tumbler” and the grit that I received with it was “generic.” At the time, I thought it was working, until I made this purchase.This grit, to me, is the “real deal.” First stage really smoothed down the rocks and the final stage grit made an amazing glossy finish on my rocks. I have yet to give my rocks a “soapy water” tumble to get rid of the white residue from the final stage grit.I like this grit a lot!!

My rock tumbler arrived in the time frame promised. I opened it up and almost immediately began to tumble stones. I am currently on stage 3 (week 3) of the machine running 24 hrs a day. No issues with the operation of the tumbler at all! Relatively quiet and smooth running machine. Very pleased with my purchase and would recommend to others.

I purchased this product to use in a 3 lbs rock tumbler which I also purchased through Amazon. Since the purchase, the tumbler has been polishing non-stop. These Tumbler Grits work very well although I would suggest that the rocks remain tumbling in the media twice as long as the seller suggest. Much finer finish and beautiful stones can be created for jewelry.

If your not sure about how much the weight is. Check it cause the picture looked like 3 large bags. I was wrong by allot. The bags are like 3" x 3" .My bad cause I didn't check the weight.

Good quality grit.
