The National Geographic Rock Tumbler Kit is an excellent introduction to an addictive hobby!
Turn rough rocks into glossy gemstones you can use to create jewelry or other crafts. It’s also a great way to encourage learning about rocks, geology, and gemology.
The National Geographic Rock Tumbler base and motor are built to last. The tumbler barrel is designed to be low noise and leak proof. It has a built in timer and automatic shut off switch too!
- Tumbling machine
- Upgraded leak-proof tumbling barrel
- 1/2 lb bag of rough gemstones
- 4 bags of polishing grits
- 1 rock strainer
- 5 jewelry settings
Note: Using a Rock Tumbler can create some sound, even with a low-noise barrel. It also takes patience. This is a project that involves several steps over many days.
