1200 Fine Aluminum Oxide, Final Polish for Tumbling Stones, Aluminum Oxide Powder Compatible with Any Rock Tumbler, Rock Polisher (Step 4, 2 Pounds)

This 2-pound EYAEYAO 1200 Fine Aluminum Oxide Powder is a premium, ultra-fine abrasive specifically engineered for the Step 4 final polish stage of rock tumbling. As the last step in the four-stage tumbling process, this 1200-grit aluminum oxide delivers a mirror-like, high-gloss finish that enhances the natural color, clarity, and veining of all types of stones—including agate, jasper, quartz, obsidian, and petrified wood.
Crafted from high-purity aluminum oxide, this ultra-fine powder is designed to remove the subtle micro-scratches left by Step 3 fine grit (600–800 grit) while creating a smooth, reflective surface. Its consistent particle size ensures uniform polishing across all stones in the tumbler barrel, eliminating uneven finishes and delivering professional-quality results for hobbyists, educators, and lapidary enthusiasts alike. The fine texture works gently yet effectively, avoiding over-polishing or damage to delicate stone surfaces.
Formulated for universal compatibility, this Step 4 final polish works seamlessly with all rotary and vibratory rock tumblers on the market. The 2-pound size is perfectly portioned for multiple large tumbler loads (ideal for polishing 5–10 lbs of rocks per cycle), making it a cost-effective choice for frequent tumbling projects. Packaged in a resealable, airtight pouch, the powder stays dry and free-flowing to prevent clumping and moisture damage between uses. Whether you’re finishing a personal collection of tumbled stones or leading a classroom rock-tumbling project, this 1200 fine aluminum oxide powder delivers the flawless, high-gloss finish that brings your stones to their full aesthetic potential.
