About This

• KoolStone's Exclusive 8,000 Grit Sub-Micron Aluminum Oxide Polish stands in a league of its own—significantly finer than typical 800-1500 grit polishes. It removes nearly all surface scratches, delivering a consistent, high-gloss professional shine on rocks, gems, and glass.
• Premium Quality Material for Final Stage: This ultra-fine 8000 grit aluminum oxide is designed for Step 5—the final polishing stage. 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 That Final Step: Perfect for rock tumblers who want a deep, glossy finish without overcomplicating the process. This 8000 grit polish brings out brilliant shine on rocks, gems, and glass—turning rough stones into smooth, lustrous specimens.
• Enhance Your Tumbling Results: Regular polish (800-1500 grit) gets you most of the way. KoolStone 8000 delivers the final polish that eliminates visible scratches and produces a clean, reflective, high-gloss appearance that rivals professional results.
• Perfect for Hobbyists and Professionals: Whether you're just starting out or an experienced rock tumbler, this polishing grit is easy to use. For best results: use 1-2 scoops per batch, add water to cover stones, and tumble for 3-5 days after completing your regular polish stage.
• Recommended Usage – Add about 2 scoops of polishing powder, and add enough water to just cover the stones. Tumble for 3-5 days, checking periodically and adding water as needed to maintain smooth rotation. Adjust polishing time slightly for larger or harder stones; if polishing results are weak, increase to 3 scoops on the next run. Optional (weight guidance): approximately 0.05LB of powder per 1LB of stones (use scoops as primary guideline).
• Best Performance Tips: KoolStone 8000 Grit Polishing Powder performs best with a professional polishing machine. 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.
