Imagine being able to turn an old rock into a gem-like stone without using a magic wand. You no longer have to be a scientist to unveil the beauty that lies within these natural artifacts. The wonders of geology can now be discovered in your own home with the aid of a rock tumbler. 

What usually takes nature a couple of thousand years can now be done within 2 to 4 weeks. For aspiring metal detectorists a rock tumbler is a very handy tool for cleaning and polishing unearthed material, giving them the shiny look that makes them ready for display. These machines are also great for making jewelry and polishing brass.

Rock tumbling works by adding rocks, water and grit to a barrel that slowly tumbles. It is fuelled by a small motor engine and eventually wears away all the sharp and rough edges of the stone, giving you a smooth silky finish over the course of a few weeks.

The 4-step tumbling process involves:

  • Step 1 – coarse grind
  • Step 2 – medium grind
  • Step 3 – fine grind / pre-polish
  • Step 4 – polish

Whilst hunting for treasures please make sure you’re aware of the laws of your local area to avoid trespassing on private land. In the US and Canada, you may find you need a permit to explore certain areas.

For our research into the best rock tumblers, we read customer reports and took recommendations from people who have experience in rock tumbling and an understanding of the process. We then analyzed our research through Fakespot to pick the best possible products for you.

FAQs About Rock Tumblers

What types of rock tumblers are there?

Rock tumblers come in 2 different types: rotary and vibratory.

If you’re a beginner you’ll want to go for a rotary rock tumbler as they are user-friendly and the most common type in use. In fact, it is probably what the majority of people will picture when they think of a rock tumbler. This covers all the bases too. Throughout the coarse grind stage, it knocks off edges, shapes, and smoothens the rough rocks out. Also, any rocks tumbled using a rotary rock tumbler always change shape to appear more rounded.

As for vibratory rock tumblers, they are less common for novice users. Unlike rotary tumblers, vibratory ones don’t change the shape of the rock. They’re usually used after a rock has been shaped since they focus on fine polishing the rock instead.

What other items can you tumble?

If you’ve found some coins during your metal detecting adventures then you can throw those in the rock tumbler. A rock tumbler will help clean it giving it a nice shine.

Something to keep in mind, however, is that you don’t want to do this for valuable coins. A rock tumbler will completely destroy that value, so they would be worth nothing more than a collector’s item for yourself. Only work on cleaning coins if they aren’t worth more than their face value or if you plan to melt them down.

Other than coins you can also place shells inside a rock tumbler.

As long as a seashell isn’t too thin it can be placed into a rock tumbler, but your approach would need to be modified since shells are far more fragile than rocks. There is no point in going through the coarse grit stage. Only spend a little time on the second stage or you can skip that completely as well, depending on the consistency of the shell.

Make sure to use as many shells as possible that will comfortably fit inside the barrel, including as much filler as you can.

To Conclude:

It is common to come across various rocks while you’re out searching with a metal detector, and if you want to reveal the beauty that lies beneath them you will need the best rock tumbler. These machines remove all the imperfections so that you are left with something smooth, like those stunning gems you typically find in precious jewelry. Rock tumblers are plentiful, however. Finding the right one for your needs can take time. We looked at a variety of products so you can find a rock tumbler with the barrel size you need, the skill level that you’re at, and the features you most require.

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.

There are a variety of rock tumblers on the market to suit beginners, more advanced enthusiasts, and even commercial use.
