My Buying Guide on ‘National Geographic Rock Tumblers’

Are you in search of a rock tumbler that is not only high quality but also educational? Look no further than the National Geographic Rock Tumblers. As a proud owner of one myself, I can confidently say that these tumblers are a great investment for both kids and adults who are interested in geology and gemstone polishing. Here is my personal buying guide to help you make an informed decision when purchasing a National Geographic Rock Tumbler.

Quality and Durability

One of the main factors to consider when buying a rock tumbler is its quality and durability. The National Geographic Rock Tumblers are made with heavy-duty materials that can withstand continuous use without any issues. The barrels are made of high-quality rubber and the base is made of sturdy plastic, making it durable enough to last for years.

Tumbler Capacity

The capacity of the tumbler barrel is another important aspect to consider. The National Geographic Rock Tumblers come in two sizes – 1 lb and 2 lbs – allowing you to choose the one that best suits your needs. The smaller size is perfect for beginners or for those who want to polish smaller rocks, while the larger size is great for larger rocks or multiple batches at once.

Noise Level

Some rock tumblers can be quite loud, which can be disruptive if you plan on using it indoors or at night. However, I have found that the National Geographic Rock Tumblers operate quietly, making them perfect for use at home without causing any disturbance.

Speed Settings

Most rock tumblers come with only one speed setting, which may not be suitable for all types of rocks or gemstones. What I love about the National Geographic Rock Tumblers is that they have two speed settings – low and high – giving you more control over the tumbling process. The low speed setting is ideal for polishing soft stones while the high speed setting works better for harder stones.

Included Accessories

The National Geographic Rock Tumblers come with all necessary accessories such as grits, polish, and rough gemstones, making it easy to get started right away. Additionally, they also come with an informative guidebook that teaches you about different types of rocks and how to identify them.

The price of a rock tumbler may vary depending on its size and features. However, I have found that the National Geographic Rock Tumblers offer great value for money considering their quality and included accessories.

In conclusion, if you are looking for a high-quality rock tumbler that provides an educational experience as well, then the National Geographic Rock Tumblers are definitely worth considering.
