Brand: KomeStone

Color: white: 8000 Grit – Fine Polish

Features:

• Step 5 Rock Tumbler Grit – Not a Grinding Powder, a Polishing Grit: Unlike the coarse grinding grits used in Steps 1–4 to shape and smooth stones, this ultra-fine 8000-grit aluminum oxide rock polishing grit works at the surface level—eliminating micro-scratches and bringing out natural gloss. Designed specifically for the final polishing stage, it delivers results that grinding grits simply can't achieve.
• Smooth, High-Gloss Finish on Rocks, Gems & Glass: The ultra-fine 8000-grit formula provides a reliable balance of polishing efficiency and surface clarity. Produces a smooth, clean, high-gloss finish on most rocks, gemstones, quartz, agate, and glass. Ideal for hobbyists and collectors who want consistent, repeatable results from every tumbling cycle.
• Premium Aluminum Oxide – Trusted by Lapidary Professionals: KomeStone uses high-purity aluminum oxide for consistent, repeatable results across rocks, gemstones, quartz, agate, glass, and jewelry components. A reliable, high-performance polishing grit that delivers deep, brilliant results across a wide range of hard materials.
• Start with 8000 Grit – Upgrade to 12000 for Even Higher Gloss: 8000 grit is the standard Step 5 polish for most rock tumbling projects. For stones that require a higher-gloss finish, follow with our 12000 grit as a Step 6. Both grits are available separately, giving you full control over your polishing process. Compatible with rotary and vibrating rock tumblers of all brands.
• Easy Usage Guide – Resealable 1 lb Container: Add approximately 2 tablespoons (0.05 lb) of polishing powder per 1 lb of stones with enough water to just cover the load, and run for 3–5 days. Packaged in a resealable 1 lb container for easy storage and reorder. Results may vary depending on stone type, hardness, and equipment.
