Transform rough rocks into extraordinary gemstones with the National Geographic Starter Rock Tumbler kit. 

Fill the leak-proof barrel with the rocks and grit provided, and then tumble away. The machine will transform them into nine different types of beautifully polished gemstones. If you like you can attach them to the five fastenings provided to make your own jewellery! A detailed learning guide describes all the gemstone specimens that you’ll add to your collection, helping you discover that geology really does rock! 

The prize

Six budding geologists  will win a  National Geographic Starter Rock Tumbler kit. Awesome!
