How Do I Choose the Best Rock Tumbler?

Hobbies. We all have them. Whether it’s scouring the beach with a metal detector, knitting scarves for every member in your family or rushing down a mountain on your cruiser. You can’t deny hobbies are a wonderfully productive way to pass the time. Have you, however, ever thought about turning precious stones into lasting treasures? Below is a little bit of information about why rock tumbling could be your next, favorite hobby.

Rock tumblers are machines used to polish rocks, gems, stones, metals and glass. The use of these machines has become increasingly popular in recent years and is no longer just a profession but a hobby. Hobbyists often use rock tumblers to shape rocks for display or even for jewelry purposes with many kits these days including jewelry making tools as well. Since there is such a wide spectrum of people using these machines, the tumblers themselves are now available in a variety of styles. They can range from desktop models for amateurs to industrial models for use in large studios.

Many people tumble rocks and gems simply for display purposes but there are actually a whole host of things you can do with your tumbled goodies that you may have never even thought of. Tumbled gems are great for making jewelry whether you are a professional or simply trying your hand at something new. They can also be used for a whole host of decoration purposes such as mosaics, picture frames, ornaments, vase fillers and sooo much more!

When looking for the best rock tumbler for you there are a few things you may want to consider beforehand. Firstly, rock tumblers come in two different styles - rotary and vibratory. It’s important to figure out which style of tumbler you are after before making your purchase.
  • Rotary rock tumblers- These are probably the most common type of tumbler for creating tumbled stones. Rotary tumblers often have barrels made from rubber to help them run quietly. We recommend purchasing this type if you are a beginner to the world of tumbling as they are easy to use and often come with instruction guides and accessories.
  • Vibratory rock tumblers- These are a lot faster in comparison to rotary tumblers and are usually more economical to operate. Often, vibratory tumblers are more expensive and require a certain level of skill and practice to operate them successfully. We recommend purchasing a vibratory tumbler if you have been using tumblers for a while and are looking to improve your skills.
When it comes to the price of your new rock tumbler, this is going to come down to the type you choose (rotary of vibratory) and the features and accessories you want included. As discussed earlier, vibratory machines are often more expensive due to their professional style. You can expect to pay between $100 and $200 on these types of machine. A rotary machine, however, is slightly less expensive due to the fact it’s for beginners. You can expect to pay anywhere from $60-$100 for these types of products.

If you are after a cheaper rock tumbler, we recommend buying a product that doesn’t include accessories such as stones, jewelry making kits and grit. Although these features are great and make your hobby easier to start, they do add cost to the machines. If you look around online you may be able to buy these accessories separately for less. However, buying machines that have these items included makes the whole process that little bit easier and also helps you to understand how to make jewelry products too. If you are a beginner to rock tumbling or buying a machine as a gif then we recommend choosing a product with accessories included.
When trying to find the best rock tumbler for you there are a few things we recommend looking out for to ensure you choose the perfect product to get you started.

Here are some key features to look out for…
  • A rubber lined barrel
  • Tumblers that can polish a variety of materials
  • Noise reducing barrel
  • Leak proof motor
  • Kits that include stones and accessories
  • Shut-off timer
Construction and Design
When choosing the best rock tumbler, we recommend buying a product with a rubber lined barrel as this means the construction is durable and well built. It’s also a great idea to choose a tumbler that can polish a variety of materials as you will have more variety in the products you can create. Plus, it’s more fun too!

Noise reducing barrels are a wise choice in our opinion as all those rocks and stones rolling around can create quite a racket! This way you won’t annoy your neighbors, parents or yourself! Leak proof motors are also a great feature to look out for as rocks can create quite a lot of dust when tumbled. A leak proof motor will prevent any nasty spillages meaning you can spend more time tumbling and less time cleaning!

Finally, we suggest looking out for a product that’s made of a sturdy material such as steel. This will mean your chosen product is built to last and can be enjoyed for years to come rather than falling apart after the first few uses.
Performance and Ease of Use
When it comes to caring for your rock tumbler it’s important to keep the barrel clean to ensure you produce the best stones and rocks possible. A clean barrel also stops the product from leaking. Now, don’t worry - rock tumblers don’t actually require much effort when keeping them clean. Simply use an old toothbrush to wipe down the rim and sides of the barrel to ensure any excess grit has been removed. Easy!

If you have purchased a rock tumbler with a rubber barrel and quality material then you won’t have to worry about the maintenance of your product. These types of machines are designed to take a bit of a battering so they are purposefully made with durable materials. Many tumblers these days also come with 1-5 years’ warranty too, so keep a look out for for that.

Rock tumblers also don’t require any installation. What a relief, eh? Most machines come ready and raring to go so you don’t have to worry about spending hours piecing your product together. If you are after a particularly high quality machine then we recommend purchasing a vibratory rock tumbler. Although they are trickier to use, they create finer quality products that will look stunning in jewelry or as part of a mosaic.
