1 Pound of MJR Tumblers Premium Quality Extreme Polish 12,000 Grit Sub Micron Aluminum Oxide Rock Polishing Powder. for Unparalleled Quality and Performance. A Disabled and Veteran Owned Company!

The best polish. Don't trust the kits on here, you need 8000 and above in final stage to get a good polish. This works really well. Always burnish afterwards to complete the stones.

GOOD STUFF! Much better than What National Geographic Sells.

This polish made my rocks SUPER GLOSSY! Definitely recommend and I will be purchasing again.

Was nice contributor to my holiday projects and was reasonably priced

It is the same as I already have , did not make stones shiny

We got some rock tumblers around Christmas and they’ve been running since then. We could never get the polished shine we expected, some of these rocks have been final polished or burnished for weeks without getting them to shine. I decided to give this product a try. It arrived four days ago and I immediately started the problem rocks tumbling in it. I just checked today and they already have a beautiful shine when dry! The grit is pricey, but you cut can cut the cost in half by buying five pounds.

Amazing. I was about to give up because my rocks were just not getting polished very smooth but not polished read the reviews for this product and decided to try it . I'm only on day 4 of polishing with the 12000 grit and my rocks already look amazing. Will 100% be buying again in the future!

Be patient tumble a long time and you will be amazed how shiny your rocks will be. Just remember that the finished piece is no better than the base underneath the final finish. Like a paint job on your car, if there are rough patches they’ll still be there at the end.
