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.

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.

I bought this geode set for my 7-year-old, and it was a huge hit! From the moment the box was opened, my child was absolutely fascinated. The set came with a great variety of geodes, and cracking them open felt like a real treasure hunt. Each one was different. Highly recommend this for any kid who loves rocks, science, or just discovering cool things. It’s a fun, memorable experience they won’t forget!

These are beautiful and fun for kids, but the results weren’t quite as spectacular as shown on the box.

Adult supervision required. Even following the instructions the rocks are very hard to break. My daughter gave up after hitting the rock ten times. Several of the rocks don't want to crack at all no matter how hard they are hit. They are messy as well. If you can get them open with out smashing them into several pieces the geodes themselves are pretty.

The media could not be loaded. Extremely fun project! Must wear eye protection! Though, they are EXTREMELY hard to open. We read the directions and reviews in order to not shatter them. It took over an hour to open the bigger ones. Still unsuccessful with the smaller ones. We tried the hammer and chissle, drill, etc. We were very careful at the same time. I wished we had more colorful ones, but these still turned out beautiful!

This is a great concept. The kids loved it. It was somewhat challenging to break, but they got them all opened. I however, was beyond disappointed that every geode in the kit was the white crystals. We were hoping for at least one colored geode for the kids, like it advertised. For the price there really should have been at least one geode with colored crystals. If there had been a colored one, this would have been a 5 star rating.

Geodes are small and easy to crack with a hammer. If your kid enjoys cracking geodes, or just like colorful rocks, these are great for the future geologist in your life.
