If your a rock collecting nut that loves to polish rocks like me, this is some of the best prices and available stage 4 polishing compound on desertcart. Batch after batch, I’ve gotten consistent results from Poly Plastics grits. Review: Pure Aluminum Oxide - Better than other brands - I get an excellent polish with this 1200 grit. 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.
