Rocks come out way shinier than when using other polish brands. For instance the Rockshed 1000 grit results in dull rocks in comparison. The Rockshed grit color is gray and under a high powered microscope you can see contamination, black particles, which make the overall color of the grit gray. Aluminum oxide, with high purity, should be white. ## Features - STAGE 4 OF 4 STEP ROCK TUMBLING MEDIA GRIT – Two 1.5 lb. jars of Stage 4 media grit for transforming rocks and gemstones into beautiful treasures.

Rocks come out way shinier than when using other polish brands. For instance the Rockshed 1000 grit results in dull rocks in comparison. The Rockshed grit color is gray and under a high powered microscope you can see contamination, black particles, which make the overall color of the grit gray. Aluminum oxide, with high purity, should be white. ### ⭐⭐⭐⭐⭐ It works! *by Y***O on July 16, 2023* I was using a Step 4 product from another company and it just didn't leave my rocks shiny. So I bought this grit to try out. I was very pleased with the results. I use a 3 lb tumbler and added 5 tbsp of this grit at my Step 4 product. After 3 days of tumbling, my quart was shiny. I think after 5 days I would have gotten super shiny rocks but I don't need that with these batches I'm working on now. This was amazing considering that the previous grit I used didn't even give me a hint of shine after 12 days. I will definitely buy again. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/382711288-polly-plastics-rock-tumbler-grit-refill-final-polish-1200-fine](https://www.desertcart.co.za/products/382711288-polly-plastics-rock-tumbler-grit-refill-final-polish-1200-fine) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-21*
