"Polish your own gemstones

Beautiful gemstones are polished, smoothed and shaped by their existence in nature and being tumbled through rivers—a process that usually takes thousands of years! Now you can mimic that same natural event with the Discovery #MINDBLOWN Rock Tumbler Kit.

Everything you need is included—just add water!

The tumbling motion, gritty sand and water are the only things Mother Nature uses to polish natural quartz and other stones. This kit takes those things and adds electrical power so speed up that natural process. Just add the stones, rocks, and the gritty sand to the tumbler and let it do all the work for you. Within days you will have smooth and polished gemstones that you can use for making accessories.

Fun and educational STEM kit

Children ages 10 and up will enjoy being a scientist with this kit! This set from Discovery #MINDBLOWN uses natural science and geology concepts to bring you a fun and educational toy!

Please note: All gemstones are natural and unique! The ones in your kit could vary from those pictured.
