- DIVE INTO THE FUN ROCK TUMBLING: KomeStone rock tumbler turns rough rocks into smooth gemstones through a real 4-stage tumbling process. Kids love watching each cycle’s transformation—a great patience lesson—and adults enjoy using polished stones for jewelry making and DIY crafts.
- 2025 NEW UPGRADE & ADVANCED FEATURES: Elevate your tumbling with a built-in LCD screen, 9-day timer, 3-speed controls, and pause/resume function. The thickened rubber barrel increases durability and improves noise reduction, while our custom polishing recipes help produce brighter, professional-level gemstones.
- 2.5 LB EXTRA LARGE CAPACITY & QUIETER: Our 100% soft rubber barrel absorbs impact for 75% quieter operation (similar to a dishwasher). The large-capacity design polishes 2.5× more rocks than standard 1 lb barrels—ideal for families, classrooms, and serious rock tumbling hobbyists.
- COMES WITH EVERYTHING YOU NEED: Includes tumbler, rubber barrel, 1 lb rough rocks, extra belts, 4 polishing grits, ceramic media, and an easy full-color guidebook—simple enough for any starter rock tumbler user to begin tumbling independently.
- SCIENCE-BACKED POLISHING FOR PRO-LEVEL RESULTS: Achieve museum-quality shine through our 4-stage grit system (60/120/150/1200) and precision ceramic media. The leak-proof stainless-steel lid ensures a clean, mess-free tumbling cycle, and our exclusive guidebook teaches pro polishing techniques for advanced users.
