Your purchase has purpose!

Every purchase helps support the global nonprofit National Geographic Society in its work to protect and illuminate our world through exploration, research, and education.

RUGGED, DURABLE DESIGN – The improved leak-proof barrel features a large 2-lb. capacity and an updated roller system to keep the barrel centered. It’s also 75% quieter than most plastic barrels, thanks to a layer of tire rubber that absorbs sound.
ALL-IN-ONE TUMBLING KIT – In addition to the professional-grade, redesigned tumbler, you get 1 lb. of rough rocks (9 different types), 5 jewelry fastenings, tumbler grit, a large strainer, and our GemFoam rock polisher to get you started right away!
PRO-GRADE PERFORMANCE – A heavy-duty, 3-speed motor and programmable timer with day/hour settings deliver consistent results. The updated LED user interface lets you easily hone your settings for precise tumbling every time.
USE GEMFOAM FOR DAZZLING RESULTS – This rock tumbler kit stands apart from others by including our reusable, patented GemFoam rock polisher! Add GemFoam and water to the barrel after your final tumbling stage and your gems will have incredible shine!
HIGH-QUALITY EDUCATIONAL TOYS – We’re proud to make the highest quality hands-on science toys, and all our products are backed by exceptional service. If your experience is less than stellar, let us know and we’ll make things right!
