Product Details

✓17000 Grit Aluminum Oxide Rock Polish for Final Finishing: Compared with an 800–1500 grit regular polish, KomeStone 17000 grit offers a higher nominal grit grade for a dedicated finishing cycle. This ultra-fine rock polish helps develop surface gloss on properly prepared rocks, gems, and glass, revealing their natural color and luster.

✓Step 5 Final Polish—A Flexible Finishing Sequence: Use this rock tumbler polish after the earlier grinding, smoothing, and regular polishing stages, or run an additional finishing cycle after 8000 grit. You do not need every grit in the KomeStone range. Add this polishing powder to your rock tumbling grit and polish routine when your stones are ready for final finishing.

✓Rock Polishing Grit for Gemstones, Glass & Display Pieces: Suitable for prepared quartz, agate, gemstones, and glass in lapidary, collection, and jewelry-making projects. This rock polishing compound focuses on the finished surface after shaping and smoothing are complete. Material hardness, preparation, load conditions, and polishing time affect the final appearance.

✓Rotary & Vibratory Compatibility—Resealable 1 LB Refill: This rock tumbler grit works with rotary and vibratory machines. Measure the loose polishing powder for individual batches and store the remainder in the resealable container. Follow your equipment’s loading instructions.

✓Recommended Usage & Preparation: Begin with thoroughly cleaned stones and barrel. Add approximately 0.05 lb of powder per 1 lb of stones, with water as directed by your machine. Use 3–5 days as an initial guide; check progress periodically and adjust for materials and equipment. Rinse the stones thoroughly after polishing.

✓Complete Your Rock Tumbling System – Full Grit Line from KomeStone: 17000 grit is the ultimate final step in KomeStone's complete multi-stage grit system. Pair with our 8000 grit (Step 5) and 12000 grit (Step 5/6) for a complete professional-grade polishing sequence. Also available: Full Stage Rock Tumbler Grit Kit (Steps 1–4) in 4 lb, 6 lb, and 10 lb sizes.
