About This

• KoolStone's Exclusive 12,000 Grit Sub-Micron Aluminum Oxide Polish stands in a league of its own—significantly finer than typical 800-1500 grit polishes. It removes the microscopic scratches that regular polish leaves behind, delivering a true mirror finish—not just high gloss.
• Premium Quality Material: Introducing KoolStone Rock Tumbler Polishing Grit, designed with ultra-fine 12000 grit aluminum oxide for superior polishing performance. Use it AFTER your regular 800-1500 grit polish, not instead of it. This 1 lb pack provides enough material for multiple tumbling projects.
• Ideal for Final Polishing Step: Perfect for rock tumblers who want more than just "bright shine." This 12000 grit acts as a high-performance finishing agent, bringing out a deep, reflective, glass-like gloss on rocks, gems, and glass—turning shiny stones into display-quality specimens.
• Enhance Your Tumbling Results: Regular polish gets you 90% there. KoolStone 12000 delivers the last 10% that makes all the difference. This ultra-fine powder smooths surfaces at a microscopic level, helping your finished pieces stand out with a clean, mirror-like appearance.
• Perfect for Hobbyists and Professionals: Whether you're just starting out or an experienced rock tumbler, this polishing grit is easy to use and delivers reliable, consistent results for achieving beautifully polished stones.
• Recommended Usage: Add about 2 scoops of polishing powder, then add water just enough to cover the stones. Tumble for 3–5 days, checking periodically and adding water as needed. For larger or harder stones, slightly extend tumbling time or increase to 3 scoops for optimal results.
• Best Performance Tips: KoolStone 12000 Grit Polishing Powder performs best in properly maintained tumblers. Suitable for rotary & vibrating rock tumblers, and for best results, ensure your equipment is clean and prepared for the final polishing stage. Beginners are encouraged to familiarize themselves with polishing steps before use.
