Rock collecting is a hobby that has captivated people of all ages for thousands of years. Historical records in ancient Egypt and India tell stories of communities using “tumbling” systems to polish rocks used for jewelry making, decoration, and more – each of which remains popular today. The best rock tumblers make your rocks look impeccable, bringing out their natural beauty. But how do you know which one is right for you? 

First, you must consider what types of rocks you’ll be polishing. Weight is the most important factor. For example, if you want to polish larger batches of rocks at a time, a six or ten-pound capacity tumbler is a better option than a smaller one. Also, consider how quickly you want the tumbler to work. A vibrating rock polisher will have your rocks clean within ten days, while a rotary rock tumbler is regarded as the most common type and completes the polishing process within 45 days. 

A rock tumbler is a necessary purchase for anyone who calls themselves a rock collector, whether you’re a beginner or a lifelong geology enthusiast. However, sometimes a rock tumbling hobby can ignite other interests in science for kids. Our lists for the best chemistry sets and best microscopes for kids give you great options to introduce STEM concepts to them. In the meantime, check out the best rock tumblers available now!
