Product details
A diamond in the rough? Turn ordinary rocks into beautifully polished gemstones with our KomeStone Rock Tumbler Kit. This tumbler kit is a great way to get kids, and adults alike, introduced to the popular habit of rock tumbling. And it's so easy to use—just insert rocks (one-pound bag included, or select your own small rocks), polishing grit, and water into the barrel; attach it to the tumbler base; and plug in the tumbler. With a little bit of patience, and a lot of anticipation, children will be amazed at the dazzling results! Turn them into beautiful pieces of jewelry, glue them on a picture frame or Christmas ornament, or add them as accents in potted plants.

Best Gift ever
Over the years I have dealt with having rocks thrown into the saddlebags on the motorcycle, a floorboard with a zip‑lock bag full of rocks, porch railings lined with rocks picked up from the yard, and quart mason jars sitting around hidden in places I didn't even know existed in the house. So this rock tumbler was one of the best gifts I think I've ever given to my rock freak. First words out of her mouth when she opened the box were “I got a rock tumbler,” and that smile said everything. I ended up getting a full Rocks 101 lesson for pretty much the rest of the day. This is one of those gifts that will make somebody smile and act like a kid turned loose in a candy store. As for the tumbler itself, it's a solid setup. The 2.5 lb. barrel holds a good amount, the motor runs smooth, and the timer and speed settings make it easy to use. The barrel seals tight with no leaks and stays put while running. It's not silent, but for a tumbler it's quieter than most. The kit comes with everything you need to get started, and it's a good choice for beginners or anyone wanting a larger barrel without spending a lot more. Watching her load up her first batch of rocks was the real win.
