    I read the reviews before I bought this, and acknowledged that many of the geodes are small. They truly are. This was a great project to keep my 6yo busy for an hour outside with a hammer. I was hoping for more diversity in color, but my child is happy.

    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.

    I bought these as a fun project to do with my kids and they did not disappoint! Four of the five rocks were beautiful geodes, one was just a nodule. The nodule was extremly hard to crack... Nothing my husband, a metal punch, and a handheld sledge couldn't handle! We will polish the inside for a nicer look. The other rocks were realitively easy to open... My seven year old was even able to crack one! They recommend the sock method, but if you want nice clean breaks I would not go that route. All in all, I am very satisfied with the product we received and will buy again!

    Reviewed in the United States on June 22, 2024
    Style: 10 Geodes KitVerified Purchase
    Each of my pictures is of a unique rock. You can see that the first two rocks look extremely normal, like a regular rock. So I basically paid for 8 geodes and 2 rocks. The smallest rock was the size of a ping pong ball, the biggest rock was about 3 inches across.
    Adult must open, we used the sock and hammer method after failing with the chisel method... the book says to try these two methods. My child could not have possibly opened any of these geodes by himself.
    The book will be nice to read together.

    Overall, not worth it for us, maybe only if you have a rock enthusiast?

    Muy divertido. Ojo para abrirlo es necesario que ayude un adulto, pues las geodas hay que romperlas con martillo. Si lo haces con cuidado te quedan bonitas. Solo falta pulir las orillas.

    Was disappointed to see that one of the geodes is broken into many pieces. An expensive kit, and should be packaged better to avoid breaking during shipment. Though the bag of rocks was opened so perhaps someone returned this set already.
