Who doesn’t love beautiful rocks? People tend to randomly collect rocks as they discover them during campaign trips, hikes, or outdoor activities. However, most of these rocks lack the visual appeal of a polished gemstone. For you to achieve this look on your stone, it may take millenniums for nature to do its work, or you can invest in rock polishing equipment/machine rock tumblers.

A rock tumbler is sold in either rotary or vibratory configurations. A vibratory model will wobble the barrel without rotating it; the vibration works faster than rotation but doesn’t smooth the stones’ edges. The rotary model turns a barrel that is full of raw stones, water, and abrasive grit. As the rocks roll, they collide against each other and the abrasive grit.

There are several rock tumblers in the market currently. However, getting the right rock tumbler for you might pose a challenge. For that reason, we embarked on reviewing 5 of the best rock tumblers in the market using our expertise and informed opinions.
