As a rock collector, I have always been fascinated by the idea of polishing rough stones and turning them into beautiful, shiny gems. After doing some research, I came across the National Geographic Pro Rock Tumbler and decided to invest in it. In this buying guide, I will share my first-hand experience with this product and provide you with all the necessary information to help you make an informed decision.

What is a rock tumbler?

A rock tumbler is a machine that uses abrasives and water to smooth and polish rough stones into beautiful gemstones. It mimics the natural process of tumbling rocks in a river or ocean, but at a much faster pace.

Why choose the National Geographic Pro Rock Tumbler?

After comparing various rock tumblers in the market, I chose the National Geographic Pro Rock Tumbler for several reasons:

  • Durable: The tumbler is made of heavy-duty metal and has a sturdy rubber barrel, making it long-lasting.
  • Large capacity: The barrel can hold up to two pounds of rocks, allowing you to polish multiple stones at once.
  • Versatility: This tumbler can be used for various types of rocks such as agates, jaspers, and quartz.
  • Complete kit: The package includes all necessary supplies such as grits, jewelry fastenings, and an informational guide.
  • Silent operation: The motor operates quietly, making it suitable for use in any room without disturbing others.

The tumbling process

Using the National Geographic Pro Rock Tumbler is simple and straightforward. Here are the steps involved in tumbling rocks:

  1. Add rocks: Start by adding rough stones to the barrel. Make sure not to overfill it as it can affect the tumbling process.
  2. Add grits: Next, add coarse grit along with water to cover the stones completely. This will help shape and smooth out any rough edges on the rocks.
  3. Tumble: Allow the tumbler to run continuously for about seven days. Check on it periodically to ensure that there is enough water in the barrel.
  4. Add finer grits: After seven days, remove the coarse grit and add fine grit along with water. This step will give your stones a smoother finish.
