Premium 500 Silicon Carbide Rock Tumbling Grit
The Stage 3 Pre-Polish I Personally Use and Trust
As a fellow rock hound and tumbling enthusiast, I know firsthand that Stage 3 is where the real magic begins. Pre-polishing is the critical bridge between a smooth stone and a brilliant, glass-like finish. To erase those final micro-scratches from Stage 2, you need an exceptional abrasive, which is why I am thrilled to offer the exact 500 silicon carbide pre-polish grit that I use, trust, and rely on for my own collection.

It is a vital addition to your lapidary supplies to ensure your stones are perfectly primed for their final polish.

Superagates Tip: Stage 3 is the secret to a great final polish! If your stones aren’t completely smooth and scratch-free after this stage, do not move on to polish—run them in 500 grit a little longer. And as always, thoroughly wash your rocks and barrel completely clean before moving to Stage 4. Happy tumbling!
