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!

been finding the polishing grits from various makers VERY hit and miss most of the products 1200 - 1500 for polish are only "Pre-polish" at best in my findings. However this super polish 12,000 is GREAT it works AWESOME even on some real soft material such as Montana wonderstone!

I purchased several other "polishes" for my rock tumbler and none of them got me that wet shiny look the Rocks seem to just get smaller. Now this stuff IS AMAZING!!!!! Not even a full 24 hours with this polish and they are so shiny!!!! I will definitely be buying more!!!

Soft and very fine. Hope this grit was done the job.

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.

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.

Best polish gritt I've found so far.

This is the exact grit we needed to get our rocks to shine. We were having a real hard time getting to that stage but since we found this and borax its a game changer!

My agates have a beautiful shine now!
