This professional rock polisher makes it fun and easy to turn rough rocks into beautifully polished gemstones, thanks to its 3-pound capacity, simple operation, and durable design. Also includes 3 pounds of rocks to tumble, 5 jewelry fastenings, grit, strainer, and our innovative GemFoam polisher.
This professional rock tumbler kit from National Geographic has all the features and accessories you’ll need to master rock tumbling, start an extraordinary rock collection, and create beautiful jewelry.
Features include a 3-pound capacity barrel; automatic shutoff timer; reliable, long-lasting motor; leak-proof tumbler barrel; and noise-reduced operation (75% quieter than plastic barrels).
This kit also includes plenty of stones (3 lb.), four levels of grit, 5 jewelry fastenings, and our innovative GemFoam to add dazzling shine to your polished stones!
This high-quality tumbler allows you to set your speed and tumbling time. When the time expires, your tumbler will automatically shut-off, allowing you to choose the perfect amount of tumble time for each grit stage. Plus, our redesigned tumbling barrel dampens sound better than most tumblers out there. The rough rocks provided (3 lbs) contain nine different gemstones from around the world, and our tumbling grit is labeled by tumbling stage to make the process even easier!
Choose your favorite gems and turn them into jewelry with the included necklace, key chain, ring, and two clip-on earring fastenings inside.
And don't forget about GemFoam, our exclusive new way to add dazzling shine to your polished rocks! Use GemFoam just like tumbling grit, simply add it to the barrel with your stones and water, then three days later marvel at the shine! GemFoam is reusable too, allowing you to create a truly impressive gemstone collection.
