National Geographic Rock Tumbling Media

Keep your tumbling hobby rolling with the ultimate polishing supplies pack from National Geographic. This pack includes 4 stages of silicon carbide polishing grit compound, 1.5 pounds of ceramic media, and 30 grams of patented GemFoam for an incredible shine on your tumbled gems! All the accessories you need to dramatically improve your polishing results.

The National Geographic Rock Tumbler Supplies pack includes everything you need to enhance your rock polishing results. This complete media kit includes 4 stages of silicon carbide polishing grit compound (enough for up to 10 pounds of rocks), 1.5 pounds of ceramic media, 30 g GemFoam, a 10 mL scoop, and easy-to-follow instructions.

Our 4-stage bulk rock tumbling grit is high-quality silicon carbide, perfect for polishing rough rocks into smooth gemstones. The grit stages provide initial shaping, smoothing, pre-polishing, and the final polish. The grit comes in secure, screw-top containers for easy storage. Adding ceramic tumbling pellets to the mix will yield even better results. Ceramic media helps distribute grit effectively, reduces noise, fills smaller batches, and minimizes rock breakage.

One of the most exciting features of this pack is the patent-pending GemFoam. This special tumbling media adds a dazzling shine to polished stones. Just add GemFoam, water, and rocks to the tumbler barrel and wait a few days for high-quality polished stones. Instructions are included for optimal results.

This pack is compatible with all rock tumblers, but for the best outcomes, use it with National Geographic rock tumblers and accessories. Order today and experience the difference!

National Geographic creates high-quality hands-on science toys, backed by exceptional service. The National Geographic Society, with a mission to inspire people to care about the planet, is one of the largest nonprofit scientific and educational organizations in the world.
