Ideal for advanced rock tumbling projects requiring an additional finishing stage.

✓HIGH-PURITY ALUMINUM OXIDE POLISHING POWDER FOR CONSISTENT RESULTS: KomeStone refined aluminum oxide polishing grit delivers reliable finishing performance across professional and hobby rock tumbling projects. Ideal for collectors, lapidary enthusiasts, craftsmen, and users seeking a more refined polished surface.

✓ULTIMATE STEP 7 POLISHING WITH KOMESTONE PROGRESSIVE SYSTEM: Use 50000 grit after lower polishing stages such as 8000, 12000, 17000, or 30000 grit to continue refining properly prepared stones. Designed for users pursuing the highest level of finishing within the KomeStone polishing system.

✓EASY USAGE GUIDE & RESEALABLE 1 LB CONTAINER: Add approximately 2 tablespoons (0.05 lb) of polishing powder per 1 lb of rocks, add enough water to cover the load, and tumble for 3–5 days. Clean rocks and barrel thoroughly between stages for the best polishing results. Results may vary depending on stone hardness, shape, equipment, and tumbling conditions.
