Kids Love Tumbled Rocks

If you have ever walked past a sign for a mineral scratch patch with a child, you will know the excitement that semi-precious stones incite in most kids.

There is something magical about seeing ordinary-looking rocks transform into shiny, colorful stones. 

Best Option: National Geographic Starter Rock Tumbler

The most popular and highest-rated toy rock tumbler on the market is made by National Geographic. The brand is well-known and reliable, and they provide excellent customer service, even if you order it on Amazon. 

The National Geographic rock tumbling starter kit (Amazon link) contains all the tools, equipment, and instructions you need to start turning rough stones into brightly polished gemstones. It even includes half a pound of raw gemstones with nine different minerals from around the world.

You get black, red, and Dalmatian jasper, sodalite, amethyst, rose quartz, aventurine, tiger’s eye, and agate.

The instruction booklet is beautifully designed and illustrated, making it easy for kids to understand. However, some adult guidance is advised, especially for young kids.

This rock tumbler is constructed from high-quality plastic, and the barrel has a thick rubber coating to absorb the impact from tumbling rocks. All mechanisms are encased by plastic so there is no risk of injury. 

It is rather loud while it is running, so it is best to keep it in the garage or basement, as the instructions suggest!

You need to run this rock tumbler for 3 to 4 weeks to get the best results. Explain to your child beforehand that the process is not instantaneous to avoid disappointment. 

The kit comes with 5 different jewelry fastenings, so kids can make their own necklaces, clip-on earrings, rings, or keychains with their gemstones.

Alternative: Classic Crafts Rock Tumbler

For children 10 years and older, the Classic Crafts Rock Tumbler kit (Amazon link) is a good option. It contains everything you need to tumble rocks, including some rough semi-precious stones, like amethyst, jasper, and agates. 

The kit contains enough grit and polish for one round of rock tumbling – you will need to buy more after the first round. 

This rock tumbler is slightly more heavy-duty. It is constructed from good quality, hard plastic. One downside is that the barrel is not rubber-coated, so it is very loud while running. 

It will not last forever, like a professional rock tumbler, but with care, it can polish a few rounds of rocks. 

The motor and tumbling mechanism are enclosed so that little fingers cannot get hurt.

The instructions that come with this rock tumbler are very detailed. If you follow them very precisely, you should get wonderful results. 

The gemstones come out looking bright and gorgeously polished. The kit includes jewelry fastenings so that kids can craft with their new stones. They can make rings, necklaces, keyrings, earrings, and brooches. 

It takes about a month to tumble and polish the rocks, so it is best to keep this noisy tumbler in the garage or basement (as far away from the bedroom as possible). 

Unlike the National Geographic booklet, this one does not include as much information about the actual stones. The Classic Crafts rock tumbler would be a great gift, along with a book about gemstones. 

TIP: One of the best ways to try your new rock tumbler is to make your own sea glass. Check out the simple step-by-step guide in the article below:
