Rock tumbling is a hobby that's been around for centuries. It's a fun and rewarding process that entails using a rock tumbler to polish rocks into jewelry, art, or home decor. A rock tumbler, or rock tumbler tumbler, is a machine that uses friction to smooth rough, dull rocks into shiny, polished rocks.

In the MOOZ Themes Reviews Lab, we've tested hundreds of rock tumblers over the years, including grinders, polishers, and sand blasters. We evaluate them for performance, ease of use, and versatility. We look for rock tumblers that are easy to use, easy to clean, and that can deliver consistent results. We also evaluate them for durability, including how much wear and tear the machine can take, as well as how easy the machine is to maintain. These rock tumblers deliver consistent results, are easy to use, and are easy to care for.

Professional Advanced Rock Tumbler Kit, include Rough Gemstones, 4 Polishing Grits, with 3 Speed Settings and Digital 9-Day Timer

AliKids Professional Advanced Tumbler Rock Kit

by AliKids

TURN ROUGH ROCKS INTO POLISHED GEMS - Make any stone sparkle and polish everyday rocks into dazzling gemstones! Simple operation and durable design.

The Professional Advanced Rock Tumbler Kit is a well-made tumbler that does a good job of polishing stones. It works well for beginners, but it rocks hard and is heavy, so it's best for experienced hobbyists. The kit includes everything you need to start polishing stones, including four polishing grits of different sizes, a sifter for removing rock dust, jewelry fastenings, and a full-color instruction manual. The digital 9-day timer is very easy to use, and it comes with an automatic shutoff feature. The kit includes nine different gemstones that come in a variety of sizes and shapes, and it's fun to experiment with them. The rocks are nicely polished after tumbling, but the process of polishing them is slow and takes a while. We also found that, while this rock tumbler does a good job of polishing stones, it doesn't always remove surface scratches. The rocks we polished were of excellent quality, but we found some small imperfections that have been difficult to remove, even after several rounds of polishing.

by Leegol Electric

Professional Features: The durable motor allows you to tumble multiple batches of rocks. An improved, leak-proof barrel is lined with rubber for quieter operation

For hobbyists, this rock tumbler is stellar. It not only gives you more control over the process than you'd get from tumbling your own rocks but it produces rocks that are finer and smoother than any of those you can buy at a rock shop. The tumbler has dual barrels, so you can make two batches at once. The dual barrels also allow you to create different types of rock, such as quartz, which is popular for jewelry, and obsidian, which is popular for decorative purposes. The tumbler comes with 20lbs of walnut shell media, which is enough for about 10 hours of tumbling. The included synchronous belt helps move the media through the tumbler, so you don't have to prop up the rocks while they're tumbling. The tumbler's controls are simple to operate, and it comes with a detailed instruction manual that tells you everything you need to know to tumble rocks like a pro.

Greate Your Own Unique GemstonesOur Rock Tumbler is an extremely popular hobby for children and adults alike.This complete rock tumblering,revamped and upgraded,makes it even easier to turn rough rocks into beautiful gems.The professionally designed rock polish learns during the polishing process,making the polishing process more fun.

The Rock Tumbler comes with everything you need to start polishing rocks, including 4 types of grit, a grit bucket, a lid with a strainer, rock polisher, media, and a user guide. The kit is beautifully packaged, and the box is sturdy enough that it will survive being dropped, which is something that a lot of rock tumbler kits fail to do. The Rock Tumbler does a good job of polishing rocks, but we found that the grit wasn't as effective as grit from competing kits. The included media is very cheap, and we found that it didn't polish rocks nearly as well as grit from competing kits. The Rock Tumbler does come with a few thoughtful giveaways, including a jewelry clasp, a strainer, and a jump starter, but we found that these don't add to the value of the kit. The Rock Tumbler is a great educational kit for kids who want to learn about rocks and geology, but it's best suited for parents who already have some of the materials needed to start polishing rocks.
