Turn ordinary rocks into dazzling gemstones with the National Geographic Rock Tumbler Kit! This STEM activity kit makes it fun and easy to transform rough rocks into beautifully polished gemstones. The high-quality tumbler features a durable motor designed to last for years, and its leakproof rubber barrel reduces sound, making it 75% quieter than plastic models. This comprehensive kit includes everything you need to get started: the tumbler, four polishing grits, a sifter, nine types of real rough gemstones, and a detailed full-color learning guide.

The simple instructions and one-touch settings make rock tumbling fun and easy. Set the timer for each tumbling cycle, and the automatic shutoff feature will handle the rest. Ideal for kids, this kit promotes an interest in geology and science while providing a hands-on, creative activity. Join National Geographic in inspiring future generations with the wonders of the natural world.
