Thames & Kosmos Rock Tumbler

The kit comes with an assortment of natural rock samples to get you started - including tiger’s eye, aventurine, rose quartz, and more - as well as four polishing grits. Use the included jewelry settings to create accessories from your specimens. The powerful, long-lasting motor is built with durability in mind: once you’ve polished the included rocks, you can continue your experiments by tumbling rocks, glass, wood, and other materials you collect on your own. The leak-proof, noise-reducing barrel and built-in timer also aid in ease of use.
The included manual and poster guide children on their rock-polishing adventures, providing usage instructions as well as scientific information about different types of rocks, how they are formed, and more.
