The National GeoGeographic Rock Tumbler Kit is an all-in-one tumbling kit with everything you need to polish your rough gemstones, jewelry fastenings, and beads. Thanks to its powerful motor, this tumbler produces quality results that are comparable to a 10-speed polisher, and it's quieter than typical tumbler barrels. There's also a removable, BPA-free strainer that lets you easily drain your tumbler. The 96-page, full-color instruction manual is thorough and easy to follow. The kit includes nine different types of gemstones, five jewelry fastenings, grit, a strainer, and our innovative new GemFoam rock polisher, and you'll get two full years of use out of each tumbler. The tumbler itself is made from durable, rust-resistant aluminum, and it's 75% quieter overall than plastic tumblers. The tumbler comes with a five-year warranty.

We picked the National Geographic Hobby Rock Tumbler Kit for its dependable performance, low price, and wide range of uses. The tumbling motor has tumbling time control settings so you can easily set it and forget it. The leak-proof barrel features a stainless-steel lid, so you can easily store the grit, mess, and polishing foam. The included five jewelry fastenings make it easy to string pearls, attach pendant chains, and attach charms to necklaces. The included grit is high-quality, and the included strainer makes it easy to rinse the grit out of the barrel. The included GemFoam rock polisher eliminates the need for a separate polishing kit. It turns ordinary grit into GemFoam, which is easier to use and lasts much longer than ordinary polishing foam. The vibrating tumbler is easy to assemble, and the manual is easy to follow. The tumbler comes with a one-year warranty.

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.

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.

The National Geographic Rock Tumbler Kit is a terrific kit for anyone who wants to learn the fundamentals of rock tumbling. The kit comes with everything you need to get started right away, from 1 lb. of rough rocks to 5 jewelry fastenings to 1 lb. of grit. All the pieces are color-coded for easy identification, and National Geographic provides detailed instructions to guide you through each process. The tumbler itself is well-built and compact, and the motor is powerful enough that you won't have to worry about under-tumbling your rocks. National Geographic's GemFoam rock polisher works particularly well with this kit, and it's a great tool to have for polishing your own jewelry, doing ceramics, or polishing stone coasters. National Geographic also sells larger versions of this tumbler, which produce larger batches of polished gems, if you're interested in expanding your collection.

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.

The 3LB professional rock tumbler kit from TURTLEDArt is a fun, educational, and easy way to learn how to create polished gemstones. This kit includes everything you need to set up your own rock tumbler, including a large 3-pound rock tumbler barrel, four polishing grits to choose from, 1lb of high-quality rough stone, a reusable TPE plastic particles, and a wear TPU belt. The rock tumbler itself is a bit on the loud side, but it's 75% quieter than competitors' plastic barrels, thanks to a layer of tire rubber that absorbs sound and is sealed with a double leak-proof closure. The tumbler comes with three speeds--slow, medium, and fast--as well as a 9-day timer that automatically shuts off when the cycle is complete, a memory function, and a clear LCD screen that displays all tumbler settings and times. The tumbler's settings are easy to adjust, and there are settings for polishing rough stones, as well as polishing them to a specific color or finish. The kit also came with instructions for polishing tiger eye and jasper stones, which we tested and found that, with a few adjustments, the tumbler worked great for those stones. The kit comes with a 90-day warranty, so the manufacturer will repair or replace any parts that break or malfunction during that time.

The Leegol Electric 3LB Rock Stone Tumbler is an inexpensive and effective option for polishing rocks and metal parts. The tumbler is constructed from durable plastic and steel, and it has a 3 1/2-inch diameter, which is large enough to hold most rock samples. The Leegol has a simple on/off switch, a 500-watt motor, and a 0.5lbs of walnut shell media. Although the Leegol's motor is noisy, it's powerful enough to get the job done quickly. The Leegol's low price also makes it a good option for hobbyists, since you can purchase a tumbler for a lower price than a high-quality polishing machine. The Leegol's 0.5lbs of media is enough for polishing most rocks, and because the Leegol is simple to operate, it's a good choice for beginners.
