Achieve consistently smooth, high-gloss results on larger batches of stones—without the frustration of inconsistent finishes or running out of grit mid-process. This complete 4-step grit and polish kit is built for serious hobbyists and high-volume tumblers, giving you the exact progression trusted by experienced lapidaries.

Perfect for those working with larger loads or multiple batches, it eliminates the guesswork so you can focus on producing beautifully polished stones every time.

This kit includes:

Coarse Silicon Carbide Grit – removes rough edges and shapes stones
Medium Silicon Carbide Grit – smooths the surface and removes coarse scratches
Fine Silicon Carbide Grit – refines texture and prepares stones for polishing
Aluminum Oxide Polish – delivers a bright, glass-like shine

This kit eliminates common tumbling issues by providing a complete, properly balanced system in one place. Each stage plays a critical role in the process—skipping or underusing any step can lead to dull finishes, visible scratches, or uneven polish.

Product Details

Polishes up to 60 lbs of rock
Includes 5 lbs of each grit and polish stage
Ideal for larger tumblers or frequent use
Trusted Lortone quality abrasives
Designed for reliable, repeatable results

If you want stones that come out smooth, glossy, and truly display-worthy—batch after batch—the process matters just as much as the equipment. This kit gives you everything you need to do it right at scale, from start to finish.
