Perfect for both beginners and experienced rock collectors. - We offer 8000 and 12000 grit polishing powders, designed for the final stages of tumbling. Unlike grinding powders, which are used in Steps 1-4 to round the stones, our polishing powders are ideal for achieving a high-gloss finish starting from Step 5. You can choose either grit based on your desired shine, offering flexibility to tailor the polishing process for optimal results. - Designed for Professional-Grade Final Polishing: KomeStone 8000 Grit Aluminum Oxide Polishing Powder is perfect for achieving a high-gloss, mirror-like finish. It’s engineered for the final step in stone, gem, and glass polishing, eliminating fine scratches and enhancing surface clarity. - Suitable for a Wide Range of Materials: Whether you’re working with gemstones, quartz, agate, glass, or other hard surfaces, this polishing powder is versatile and reliable. Use it for both hobby and professional projects to bring out the best in your materials. - Easy Application – Recommended Usage: Mix 2 tablespoon of powder with water to create a smooth paste. Use it in a rotary or vibratory tumbler for 3–5 days, adjusting the polishing time and powder quantity based on the hardness and size of your material. Always ensure the tumbler is running smoothly for optimal results. - Achieve Professional Results with the Right Equipment: Our 8000-grit polishing powder works best with a professional polishing machine. While it can be used in a rotary tumbler, results may not meet expectations. If you're unfamiliar with polishing powders or equipment, we recommend learning more before ordering. If you're experienced and still wish to proceed, please consider carefully before purchasing. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CRRH1K7J | | Best Sellers Rank | #174,076 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #105 in Tumbling Media | | Brand Name | KomeStone | | Compatible Material | Glass, Stone | | Customer Reviews | 4.3 4.3 out of 5 stars (133) | | Grit Material Type | Aluminum Oxide | | Grit Number | 8000 | | Grit Type | 8000 | | Included Components | 8000 Grit for step 5: Aluminum Oxide | | Item Dimensions | 5 x 5 x 5 inches | | Item Type Name | Rock Tumbler Polishing Grits | | Item Weight | 16 ounces | | Manufacturer | KomeStone | | Material Type | Aluminum Oxide | | Number of Items | 4 | | Number of Packs | 4 | | Part Number | KS1225PG63 | ## Product Details - **Brand:** KomeStone - **Grit Material:** Aluminum Oxide - **Grit Type:** 8000 - **Item dimensions L x W x H:** 5 x 5 x 5 inches - **Material:** Aluminum Oxide ## Images ![Rock Tumbler Grit - 8000 Grit Aluminum Oxide Polish for Final Step 5, Ultra-F... - Image 1](https://m.media-amazon.com/images/I/41rHXyUTgZL.jpg) ![Rock Tumbler Grit - 8000 Grit Aluminum Oxide Polish for Final Step 5, Ultra-F... - Image 2](https://m.media-amazon.com/images/I/517g2TuVJuL.jpg) ![Rock Tumbler Grit - 8000 Grit Aluminum Oxide Polish for Final Step 5, Ultra-F... - Image 3](https://m.media-amazon.com/images/I/51hqCAl8nWL.jpg) ![Rock Tumbler Grit - 8000 Grit Aluminum Oxide Polish for Final Step 5, Ultra-F... - Image 4](https://m.media-amazon.com/images/I/61z83fIunmL.jpg) ![Rock Tumbler Grit - 8000 Grit Aluminum Oxide Polish for Final Step 5, Ultra-F... - Image 5](https://m.media-amazon.com/images/I/71TyncnAHqL.jpg) ## Available Options This product comes in different **Color** options. ## Frequently Bought Together - KomeStone Rock Polisher 8000 Grit Aluminum Oxide Polishing Grits – Step 5 Final Stage for Rock Polishing, Fine Abrasive Polishing Podwer for All Kinds of Stones, Gems, and Glass Polishing - 10 lbs Rock Tumbler Grit - Tumbler Media Grit,Rock Polishing Grit Media, Works with Any Rock Tumbler, Rock Polisher, Stone Polisher,COARSE 60/90 Silicon Carbide Grit, Step 1 for Tumbling Stones - 2 LBS Rock Tumbling Ceramic Filler Medi Rock Tumbling Ceramic Filler Media Non- Abrasive Ceramic Pellets for All Type Tumblers 3/16" X 3/8" --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/615784951-rock-tumbler-grit-8000-grit-aluminum-oxide-polish-for-final](https://www.desertcart.jp/products/615784951-rock-tumbler-grit-8000-grit-aluminum-oxide-polish-for-final) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-05*
