Frequently Asked Questions

What is Rock Tumblers?

rock tumbler is a simple machine used to polish rocks. Many jewelry makers and precious stone hobbyists use this tool to produce tumbled stones. Through tumbling, it transforms a rough piece of rock into a nice-looking stone.



Rock tumblers come in two basic varieties: rotary tumblers and vibratory tumblers. Rotary tumblers are easier to use, more affordable, and work quieter, but they utilise more grit and are prone to leaking. Meanwhile, the vibratory tumblers have more speed in tumbling and use less grit but they can be more pricey, noisy, and difficult to use

What are the advantages and disadvantages of Rock Tumblers?

Rock tumblers can be used to polish jewelry and get rid of the rough edges of jump rings. You can make a rock look nice in just a few tumbles. Other things you can do include cleaning coins, creating various crafts, and making sea glass. However, they can be tricky to use in the beginning so you need to practice several times.

What’s the approximate price range for Rock Tumblers?

The price of rock tumblers may range from £49.99 to £800.

What should I look for when choosing a Rock Tumblers?

One of the most important features that you should look for is the barrel size. The size is often expressed in weight and the standard size is 3 lbs. A 3 to 4-lb tumbler is sufficient for beginners while a 6 to 12-lb tumbler is ideal for more serious folks. For commercial use, settle for bigger machines that are 20 to 40 lbs in weight.


Another feature that you should pay close attention to is the barrel material. Barrels can either be made of plastic or rubber. Plastic barrels are less expensive but they’re not durable. We prefer the rubber barrels because they’re less noisy and they offer enough cushion to protect the rocks from damage.


If you want to tumble different kinds of rocks at the same time, look for a multi-barrel tumbler. You may also want a long warranty to ensure durability and extend the life of your tumbler.

How long does it take for a rock tumbler to work?

Approximately, it takes at least one week for a rough rock to turn into polished stones. The time may vary depending on the type of rocks and tumbler you used. Rotary tumblers usually take 4-8 weeks while vibratory tumblers only take 1-2 weeks.

What is the grit in a rock tumbler?

The grit is found inside the barrel and what makes the rocks smooth. It works like the sand that nature utilises to polish rocks. Like a common sandpaper, grit also comes in different levels of coarseness.

What is the best rock tumbler for glass? Why is the best?

The Thumler’s Tumbler Rock Polisher is the best for glass because it does a great job in smoothing the rough edges at a short time. Using the three grits that are included with the unit, glass is done in about 8-12 days. The construction of the machine is also sturdy which makes it more appealing to buy.
