Review: Un coffret bien rempli avec des géodes de bonnes tailles. Pas encore ouvertes. Review: 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. Updated 3/16/26 One geode was solid. My son lost interest before I realized it was solid because he was not able to crack it open. I suggest if one seems too difficult, move on and return to it last. I still recommend this; it was a fun activity, plus the sparkly geodes are easy to display and make a great keepsake.

Do you need to have a separate tool for that?** A: The best way to open them is to take a large file & carefully cut a groove around the Geode along any depressions in the shape. Place in on a towel on a concrete floor. Be sure to put on safety glasses! Take a large chisel and place it in the groove. Strike the end of the chisel with a hammer to break the Geode open. Be careful everyone standing near has their safety gasses on as well! **Q: Can use a sharp,big knife or if not, what do you use** A: Please do not even consider attempting this with a knife. That is an E.R. trip in the making. We were quite successful with a hammer and wide chisel. **Q: Does the item include a hammer?** A: If you don't already have a hammer, this item is not for you. **Q: Are they fake** A: They are real just not real impressive. You're better off to buy bigger geodes online. The kit has nothing spectacular you need. My package was full of solid rocks. Took a 5 lb sledge to get the apart. 100% waste of money. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by Q***E on 1 January 2025* Un coffret bien rempli avec des géodes de bonnes tailles.
