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 OPAVIOC, our exclusive new way to add dazzling shine to your polished rocks! Use OPAVIOC just like tumbling grit, simply add it to the barrel with your stones and water, then three days later marvel at the shine! OPAVIOC is reusable too, allowing you to create a truly impressive gemstone collection
