Chasing the final polish.. for the finest you'll need the finest..
You’re buying more than just diamond powder; you’re buying versatility.

These diamonds aren't only for polishing gemstones.
It’s your go-to for restoring scratched glass, flattening metal tools, smoothing ceramics, fine-tuning optics, refreshing jewelry, and even sprucing up marble or tile
This delivers precision from pre-polish to mirror finish across hard and soft materials alike.

You can load it into a felt wheel, press it into leather, burnish it onto wood, or—if you’re feeling fancy—mix it with a few drops of glycerin and make your own diamond paste. Need it thinner? Use water. Going oil-based? Baby oil or DPG works just fine. Still not cool enough? Bind it into resin and make your rotary abrasives.
No chemistry degree required.

Whether you're dialing in a final polish or experimenting with a new grit series, these abrasives give you a professional-grade option without buying in bulk.
Just enough to test, plenty to finish.
