• KoolStone Rock Tumblers for Every Level: Choose from our versatile lineup: the C1 and C1 Pro (2.5 lb capacity; Pro features a brushless motor for quieter, more efficient operation), the C1 Pro Max (3 lb capacity with noise-reducing cover), and the C1 Pro Ultra (dual barrel, 7 lb capacity, brushless motor, and noise-reducing cover). Each tumbler is designed to deliver consistent, high-quality results for both beginners and experienced rock collectors.
• Final Stage Polishing Powders: We offer 8000 and 12000 grit polishing powders, designed for the last stages of tumbling. Unlike grinding powders used in Steps 1–4 to shape and smooth stones, our polishing powders are ideal for Step 5 and beyond to enhance natural gloss and surface clarity. You can choose either grit based on your desired finish, providing flexibility to optimize your polishing process.
• Professional-Grade Final Polishing: KoolStone 8000 Grit Aluminum Oxide Polishing Powder is engineered for the final step in stone, gem, and glass polishing. It reduces fine scratches and improves surface clarity, delivering precise, consistent polishing results.
• Versatile Material Compatibility: Suitable for gemstones, quartz, agate, glass, and other hard surfaces. Ideal for both hobbyists and professional rock collectors, ensuring reliable results across a wide range of materials.
• Recommended Usage – Add about 2 scoops of polishing powder (use the included scoop), 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).
• Achieve Optimal Results with the Right Equipment: KoolStone 8000 Grit Polishing Powder performs best with a professional polishing machine. It can also be used in a rotary tumbler, but for consistent, high-quality results, we recommend equipment suited for fine polishing. Beginners may want to familiarize themselves with polishing powders and tumbler operation before starting.
