Be rock star! Design a virtual jewelry by tumbling an ordinary rock of your choice to create a one-of-a –kind gem. A diamond in the rough? Let's find out! First choose your rock, drag it to the tumbler, then press the "tumble" button. When it's done, turn your gem into a key chain, ring, bracelet, or necklace. Print your creation and show off your designer status! Gem-O-Matic was inspired by the Play! Scholastic TM toy, Rock Tumbler. Transform rough rocks into semi-precious gemstones! Includes electric tumbler, barrel, rough semi-precious stones, and more. Available exclusively at Toys R Us® and through the Scholastic Store!
