National Geographic Platinum Series Rock Tumbler

Turn raw stones into things of beauty with this professional-quality rock tumbler from National Geographic! This rock tumbler is designed for indoor use — it's quieter than a modern dishwasher. The large 2-pound barrel lets you polish lots of rocks at once, and the patented agitate mode reduces breakage so you'll get gorgeous specimens. The kit also includes patented GemFoam polisher for a brilliant finish and shine! This set comes with everything you need to get started, including four bags of grit and one pound of rough rocks to polish.
