I recently purchased the National Geographics Rock Tumbler and I must say, it has been one of my best purchases yet! If you’re someone who loves collecting rocks and turning them into beautiful polished gems, then this rock tumbler is definitely for you. In this buying guide, I will share my personal experience with the National Geographics Rock Tumbler and provide you with all the necessary information to help you make an informed decision.

What is a Rock Tumbler?

First things first, let’s understand what exactly a rock tumbler is. A rock tumbler is a machine that uses abrasives and water to smooth out and polish rough rocks, minerals, and gemstones. It works by tumbling the rocks in a barrel for several days until they are shiny and smooth.

Why choose National Geographics Rock Tumbler?

There are many rock tumblers available in the market, but I chose the National Geographics Rock Tumbler for various reasons:

1. High-Quality Materials: The tumbler is made of high-quality materials which ensure its durability and long-lasting performance.

2. User-Friendly: The tumbler is very easy to use, making it suitable for beginners as well as experienced rock enthusiasts.

3. Quiet Operation: Unlike other tumblers that can be noisy, the National Geographics Rock Tumbler operates quietly, making it suitable for indoor use.

4. Different Speed Settings: The tumbler has three different speed settings that allow you to control how long it takes to polish your rocks.

5. Large Capacity: The barrel of this tumbler has a capacity of 2 pounds, which means you can polish multiple batches of rocks at once.

Things to Consider Before Buying

Before purchasing the National Geographics Rock Tumbler, here are some important things to consider:

1. Budget: The price of this rock tumbler may be higher compared to other models in the market. However, its quality and features make it worth the investment.

2. Noise Level: While this tumbler operates quietly compared to others in the market, it still makes some noise during operation. If you live in an apartment or have noise-sensitive neighbors, you may want to consider using it during daytime hours or investing in soundproofing materials.

3. Space Availability: This tumbler requires a decent amount of space due to its size and noise level during operation. Make sure you have enough space before purchasing it.

Tips for Using National Geographics Rock Tumblers

Here are some tips that I found helpful when using the National Geographics Rock Tumblers:

1. Read Instructions Carefully: Before using the tumbler for the first time, make sure to read the instructions carefully as they contain important information on how to properly operate and maintain your rock tumbler.

2. Choose Proper Rocks: Not all rocks are suitable for tumbling. Make sure to choose rocks with similar hardness levels for best results.

3 . Don’t Overfill Barrel: Overfilling your barrel can cause damage to your machine or uneven polishing results. Follow the recommended capacity guidelines provided by National Geographic.

4 . Use Different Grits: To achieve a smooth finish on your rocks, use different grits (coarse, medium & fine) during each stage of tumbling process.

Final Thoughts

Overall, I highly recommend investing in the National Geographics Rock Tumblers if you’re interested in turning rough rocks into beautiful polished gems at home. Its high-quality materials and user-friendly design make it perfect for both beginners and experienced users alike. With proper care and maintenance, this rock tumbler will last you for years!
