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. Review: Great Present - My husband loves these. I bought them for his birthday and he was so excited he cracked them all at once just after opening them. The geodes were pretty and a nice size. I only wish they were more colorful. The ones I received were mostly white. I did have one that was slightly brown. I can't wait to get more. ## Features - BIG GEODES WITH CRYSTALS - This super-fun science kit includes 5 jumbo, uncracked geodes to break open at home!

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 ### ⭐⭐⭐⭐⭐ Beautiful & Fun *by H***L on February 25, 2026* I bought these for myself. I'm 37 years old.

The geodes were pretty and a nice size. I only wish they were more colorful. The ones I received were mostly white. I did have one that was slightly brown. I can't wait to get more. ### ⭐⭐⭐⭐⭐ Fun for my 8 yr old son! *by A***G on February 6, 2026* 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. Hope this is helpful! ## Frequently Bought Together - NATIONAL GEOGRAPHIC Break Open 5 Jumbo Geodes - Earth Science Kit with 5 Premium, Extra-Large Geodes with Crystals, Goggles & Display Stands, Science Gifts, Fun Stuff for Kids (Amazon Exclusive) - INCLY 5 PCS Geology Rock Pick Equipment Kit, 32 oz.
