Fine smoothing before final polish

Stage 3 is where you prepare the stone for a high shine. Fine F400 grit erases the last remaining surface marks from Stage 2, doing the precise work required to leave a smooth, soft finish so your final polish delivers an even, deep gloss.

Silicon Carbide is inexpensive and incredibly versatile, making it suitable for a wide range of minerals and rocks. It is most notably the best choice for hard minerals rated 7 or higher on the Mohs scale, such as quartz, agate, jasper, flint and petrified wood, which are classic choices for rock tumbling, particularly when starting out. The combination of high hardness, grain angularity and low cost make it an excellent, accessible choice for lapidary work of all kinds.

Second Only to Diamond

When it comes to shaping, smoothing, and prepping rocks for a high polish, Silicon Carbide is the benchmark for performance. Produced at high temperatures to achieve an incredible 9.5 Mohs hardness, this high-grade synthetic abrasive is second only to diamond in raw cutting power.

Stays Sharp as it Works

What makes Silicon Carbide unique is its self-sharpening fracture pattern. As your barrel rotates, the particles continuously break down into smaller, razor-sharp micro-facets rather than rounding off into smooth grains. This guarantees aggressive, uninterrupted cutting action throughout every phase of your cycle, whether you are grinding raw rock edges or buffing out deep surface scratches.

Heavy-Duty Reusable Pots
