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!
