Many people, young and old alike, enjoy the hobby of rock polishing. Along with the satisfaction of seeing and holding a shiny, smooth final product you can use in a variety of crafts or displays, rock polishing kits are perfect gifts for the rock hound in your family who spends a lot of time digging for the perfect mineral chunk. The most important tool, the tumbler, should have a sturdy base, all-metal construction, and sized to your needs—the bigger the rocks, the larger barrel you’ll need. Eventually, you’ll also need more grit, which goes inside the tumbler, to polish more material, have a selection with different coarseness ratings nearby. After you have everything you need in front of you, the process is simple and fun.
