NATIONAL GEOGRAPHIC Rock Tumbler Media Kit - The Ultimate Rock Polishing Supplies for Ages 8 and Up

From the brand, the National Geographic Rock Tumbling Media is a complete set of polishing supplies that will dramatically improve your rock tumbling results. Included in this pack are 4 stages of high-quality silicon carbide polishing grit compound, 1.5 pounds of ceramic media, and 30 grams of the patent-pending GemFoam – all the accessories you need for an incredible shine on your tumbled gems.

The 4-stage bulk rock tumbling grit is perfect for polishing rough rocks into smooth gemstones. The first stage provides initial shaping, the second smooths rock surfaces, the third pre-polishes, and the fourth delivers the final polish. Packaged in secure, screw-top containers, this grit is easy to store and use.

Adding the ceramic tumbling pellets to the mix will yield even better results. The ceramic media helps to more effectively distribute the grit to rock surfaces during tumbling, reduces tumbler noise, serves as filler for smaller batches, and minimizes rock breakage through every grit cycle.

The standout feature of this kit is the new GemFoam. Specially designed to add dazzling shine to polished stones, simply add GemFoam, water, and rocks to the tumbler barrel, and in a few days, your stones will have a high-quality polish. Easy-to-follow instructions detail how to use all the tumbling media for optimal results.

This pack is compatible with all rock tumblers, but for best results, use it with National Geographic rock tumblers and tumbling accessories. National Geographic is proud to make the highest quality hands-on science toys, and all products are backed by exceptional service.

Every purchase helps support the global nonprofit National Geographic Society in its work to protect and illuminate our world through exploration, research, and education. Order the National Geographic Rock Tumbling Media today and take your rock tumbling hobby to the next level!
