How to Make Your Own Tumbled Gemstones with National Geographic Hobby Rock Tumbler

The National Geographic Hobby Rock Tumbler is a great way to make your own unique tumbled gemstones! With this fun and easy-to-use rock tumbler, you can create beautiful, polished stones for jewelry or use them for decorations in your home.

To get started, assemble the machine according to the instructions. Then, fill the barrel about halfway with rough rocks and add enough water to cover them. Add two tablespoons of tumbling grit, which you can purchase from any hobby store or online. Now your rock tumbler is ready to start tumbling!

Next, turn on your rock tumbler and let it run for several days. During this time, the rocks will be polished by the friction caused by the grit and water. Once the rocks have been sufficiently polished, shut off the machine and rinse off the stones with cold water.

Now that your rocks are polished, you can add some color to them! To do this, mix up a dye solution using a tablespoon of dye powder in one cup of water. Put your rocks into this solution overnight. The next day, take them out and rinse off any excess dye with cold water.

Finally, seal the stones with a clear acrylic spray sealant so they will maintain their beautiful shine and color for years to come. You now have your very own handmade tumbled gemstones thanks to the National Geographic Hobby Rock Tumbler!
