Discovery #Mindblown 18-Piece Rock Tumbler

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. 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.
