Rock tumbling is an excellent activity to introduce young scientists to geology. It’s a relatively simple process. Simply add rough rocks, grit, and water to a rock tumbler and let it do its job. To take a stone from rough to jewelry ready is a process that takes several weeks. As a result, rock tumbling can also be a lesson in patience. Most rocks require a four step smoothing process that includes the coarse grind, medium grind, fine grind, and finally, polish.

Rock tumbling is a fun hobby that can be enjoyed by people of all ages. This article will break it all down and help you choose a tumbler that best suits your individual needs.
