Rock Tumbler Grit - 8000 Grit Aluminum Oxide Polish for Final Step 5, Ultra-Fine Abrasive Powder for Rocks, Glass, Gems & Jewelry Making - Premium Polish Refill for High Gloss Finish

We are new to rock tumbling, and this stage 5 grit was fun to play with. It is a very fine powder, and it gives the rocks a nice shine! It really does work nicely. This is a nice sized container that will tumble several loads of rocks. We ran it for 5 days with rocks that had been through stage 4 on speed 1. I'm looking forward to using it again!

The best thing about this product that I like is the results I’ve had polishing grit before that’s supposed to polish rocks however, it did an OK job but this stuff doesn’t excellent job 4 Four days in the Tumblr on one or two in the rocks shine like diamonds what more can I say great value for the money

Worked great on my rocks I used it as a fifth stage for polishing

Works good

I used this for a stage 5 polishing at 3 days on speed 2, and it looks very similar to my stage 4 grit. I'm still fairly new to rock tumbling, so it could be something I'm not doing right. I know I have to make sure the rocks aren't much softer or harder than the rest of the rocks in the tumbler, and not being a geologist, I don't know if my rock identification is accurate. Also, any coarser grit leftovers needs to be thoroughly cleaned from the tumbler and crevices in the rocks, or it it can cause the rocks to not polish correctly.The powder is finer than my stage 4, so it should polish more. I will keep trying until I get that diamond like mirror finish. When this product is gone, I probably won't buy it again because it's priced higher than my other brand I use.

Good for Glass Stove counter tops too !Produces a fine polish !!A +

The size was correct, unable to use polish at this time as it is not that point in my tumbling, it was not the value for the money I spent as the container was opened and spilled all over the inside of the shipping bag, not box.

I was hoping to get more impressive results from this fine grit. After doing 4 rounds of tumbling with 1-4 grits, I gave this a try on speed 1 for 7 days. Perhaps I should have included a drop or two of oil, or been much more careful about the rocks I tumbled (as some may have had small fissures). But they don’t feel any smoother nor do they look more finely polished. I’ll try again with a new batch and hope for better results. Otherwise it seems like it is a waste of time and money. I will read other reviews to see if I am missing something or a step that might improve my results. 🤞
