Frequently asked questions
The kit includes 10 premium geodes, a pair of safety goggles, and display stands. It is designed to provide an educational and fun experience for children interested in geology and science.
The kit is recommended for kids aged 8 and above, due to the need for using a hammer or other tools to break open the geodes, as well as the presence of small parts and choking hazards.
Safety goggles should be worn to protect eyes. Place the geode inside a sock or cloth to prevent fragments from scattering and gently tap it with a hammer until it breaks open to reveal the crystals inside.
Kids can learn about geology, crystal formation, and earth science. They'll get hands-on experience with rock and mineral properties, and the excitement of discovery as they uncover the unique crystal formations within each geode.

Great gift for a 5 year old rock lover who says he’s going to be a geologist. Nice size Geodes are a little hard to open without the help of an adult. A little messy, but worth it!

Style: 4 Geodes Kit
The media could not be loaded. We recently purchased this geode kit to do with the family as a Christmas gift! and it exceeded all our expectations! The kit included everything needed for a fantastic rock-breaking adventure: 4 rocks to smash and/or chisel, clear instructions, protective glasses, and a magnifying glass to examine the treasures within. We were thrilled to discover 3 amazing geodes, each with beautiful, sparkling crystals inside. One of the 4 rocks turned out to be a solid piece of crystal, which, while smaller than the rest, was still a delightful surprise and not at all a deal breaker. We used the chisel method for two of them and had to use the towel and smash method for the hard to open ones. Our 8 y/o kid absolutely loved the experience! This kit provides an excellent hands-on learning opportunity, perfect for children and adults alike. Overall, a wonderful purchase that brought joy and excitement for family fun. Highly recommend for anyone interested in geology or just looking for a fun and educational activity. Will buy again for sure.

We have only opened the smallest geode using the pointed end of the tool shown in the picture. He found it easy to open. However, we tried to open one of the larger ones, but it proved to be more challenging. I’m glad I bought the tools because using a hammer alone wouldn’t have worked well. We’re excited to open the rest of them. I did not find the process messy.

My 12yr old kid enjoyed breaking them open. 3 were tuff to crack- ended up clamping in a vice & using a chisel. Good value 80% had crystals.

My 5-year old great-niece (and her daddy) LOVED opening the geodes to see the crystals inside! The kit was a big hit at Christmas. The Nat Geo kits offer learning opportunities that are engaging for both kids and their parents!

The media could not be loaded. I bought these for myself. I'm 37 years old. They were difficult to open. Some broke in smaller pieces but we're still really cool. I love all things crystals & stones. I will for sure purchase again. You can't guarantee with nature, so it can be a hit or miss. 2 of mine were solid, but still looked like clear quartz. I'm happy.

Style: 10 Geodes Kit
We were excited to try the National Geographic Break Open Geodes set because it sounded like a great hands on science activity. The idea is fantastic and it definitely creates excitement for kids. What we liked: It comes with 10 geodes, goggles for safety, and display stands, which is a nice complete package. Breaking them open feels like a real discovery moment, and it is a good way to introduce kids to geology in a fun way. What could be better: The results really vary. Some geodes were interesting inside, but a few were smaller than expected or did not have very impressive crystals. It also requires adult supervision and the right tools to break them safely, which is something to keep in mind. For the price, I expected a little more consistency in quality. It is still a fun activity, but not every geode will be a wow moment. Overall, I would give it 3 out of 5 stars. Great concept and educational value, but the experience depends heavily on what you get inside each geode.
