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 science teacher gift :)
Style: 10 Geodes Kit
I was looking for a great gift for the science teacher and knew the whole mug thing wasn’t going to hit the mark for someone who had been teaching for decades. I am sure her cabinets are full! - So I spent some time searching on Amazon to find an appropriate and special gift, but all I really knew about her was she had made science understandable and interesting for the teens in the small private school which was no small feat science my daughter hated science in the past. After perusing the offerings for about 30 minutes, I settled on the geodes kit from National Geographic. Here is what I thought it had going for it: 1. It was science related with a reputable name behind it. 2. It was a quick-and-easy-to-explain activity if she wanted to do it with older or younger kids or grandkids. 3. It was a hands on experience and a physical gift at the same time. 4. It was pretty. As a lady, I knew I liked pretty, sparkly rocks (usually in jewelry form though) - so I was hoping she would too. 5. It was in my price range. After giving the gift, we discovered the teacher had a special interest in rocks. So it was a good match. It is nice to feel like you purchased a gift that is well received and won’t be collecting dust. She has already made plans to open some of the geodes during a class this year. Thus far it is a raging success. During my research, I discovered that scoring an equator around circumference and using a hammer/chisel to open produced a better outcome than just using a hammer. The hammer alone seemed to produce smaller sections and some crumbled. I would also suggest using some type of holding mechanism, if possible, like a vice with foam padding around the geode. I noticed that many of the people in the videos were afraid to hold it in place while they were striking it to open. Once they are opened in class I will update the review with any feedback I get. Update: Everyone loved it and the teacher made a point of mentioning how much it meant to get a special and thoughtful gift. ... show more

    • Great for kids
Style: 5 Jumbo Geodes Kit
These were awesome. Our kids absolutely loved them. They do make a big mess but so worth it. The crystals in them were very nice we did get some colored ones. Instruction are in box. We did drill a whole in one and it was easier to open up. Definitely wear the eye protection because pieces do fly everywhere. So much fun for any kid who loves crystals or rocks! ... show more

    • Excellent fun!
Style: 5 Jumbo Geodes Kit
I bought these for my husband and our grandson (3). They had a great time hammering away on the rocks and revealing the crystals inside. While my grandson had fun using the hammer, in the end it took some concerted effort from my husband to split the stones. Beautiful crystals inside. We kept half of a stone, adding it to our rock garden and our grandson took the other half home with him. And we have more stones to split at a later date. Win/win. Worth the buy. ... show more

    • Really amazing
Style: 5 Jumbo Geodes Kit
Please wear the safety glasses (we did and were thankful as a piece of rock hit the glasses and could have been his eye) I gave it 4 stars because 2 of the 5 were felt extra heavy and turned out more of a solid crystal formation and was not able to be broken open (we are looking to get something to maybe cut them open). Otherwise it was a lot of fun and very beautiful… a bit messy but in a good way. BTW this was for my 40something husband… not just for kids. ... show more

    • Good quality/decent size
Style: 5 Jumbo Geodes Kit
I ordered these geodes for a friend that started rock collecting. It was quick shipping and they were well-protected. The sizes varied from ~4 inches to 5.25 inches. When cut, there were nice crystal formations in all of the geodes. Some were opened with a tile saw/rock saw; one was opened with a hammer. Some were fairly clear, a couple were milky white and one had a nice grey tone. I recommend using a chisel if you are using a hammer and go slow. A hard hit with a hammer will get you inside but cause a lot more damage/pieces. ... show more

    • Great value and fun!
Style: 10 Geodes Kit
I bought this box to teach kids about how beauty comes from within. They had a blast wearing the safety goggles that it came with and then after looking at the crystals through the magnifying glass that it also came with. We had geodes of all different colors. A couple were on the smaller size, like a golf ball, but most of them were the size of a cutie orange or an avocado. The value was also amazing, I was at a store the next day and 1 geode was selling for over $9, so this box was well worth the value and it included the safety glasses, a learning pamphlet and the magnifying glass. I highly recommend this product! I will say we hit the geodes several times and very hard before they cracked open so another time I would try scoring the geode that is suggested. ... show more

    • Not a good value
Style: 10 Geodes Kit
The geodes were poor quality, most shattered under a hammer, no wet saw available. There is no colored quartz, mostly all white. rocks are too hard for kids to break. Takes all the fun out when dad has to do it.

    • One of My Grandson's Favorite Things!
Style: 10 Geodes Kit
These geodes are great for getting children interested in geology and science. My grandson loves to smash these with a hammer. The generally break in just two pieces (sometimes three or more), and the revealed treasures help to spark creativity. For instance, my grandson did some studying about the different crystals he discovered in these geodes, and he made a video talking about them with great enthusiasm. He named the different types of crystals and some of their properties, also demonstrating how he opens the geodes. In short, this set is a great way to get a child interested in crystal science. ... show more
