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 ### ⭐⭐⭐⭐⭐ Un excelente momento *by K***O on 25 January 2026* Padrisimoooo mi hijo se divirtió muchísimo abriendolas! ### ⭐⭐⭐⭐ Love it *by C***N on 31 March 2022* Great set but be warned, these are quite hard to open.

Bought and opened twice, beautiful crystals each time. *by I***. on 2 January 2020* We've gotten two of these kits, one several months ago for my daughter's 7th birthday (first image, with the organizer), and one for Christmas for her older sister (second image, by request after seeing her sister's birthday geodes). Both times we were very happy with what we had gotten, and I love the educational value, not just the geodes inside. The kids were fascinated and really enjoyed seeing what was inside. It's kinda like those kinder eggs/surprise toys, but naturally created! I have since bought a 3rd set when it was on sale (not opened yet). Yes, for the most part they are all white, however the first kit did contain crystal that was very pale purple (possibly amethyst?), and the second kit contained a milky pink mineral with a small crystally agate section. The first kit we had were mostly around 2 inches, the second kit had a wider range, of a couple really small 1 inch ones but a couple in the 3-4 inch range. Both kits we had resulted in a variety of hollow and full geodes, and varying size of crystal points, some small very glittery looking ones, and larger clearer ones. The second kit we had did contain a kind-of-dud, where there were tiny crystals, but mostly rock, but that was only one out of now 20 geodes we've opened from NatGeo. We have tried a different brand of break-your-own-geodes in the past, and they resulted in very few crystals (only around 20 to 30% had crystals), so I was very pleasantly surprised at what we got with the NatGeo kits. I might try to sand/polish a couple at some point. They were difficult to open, and did require adult assistance. I used a dremel to score the perimeter and provide a groove for the chisel to sit in (my dremel/dremel bits weren't strong enough to get through the crystal, just the outer rock), and then we used a chisel and hammer to crack it open. My kids were able to hammer some of the smaller ones open (with assistance holding the rock and chisel). But some, especially the solid ones, were still very difficult to crack open. Those took more time, but I (a petite, but persistent, female adult) did manage to crack them open with the chisel and hammer. In terms of "giftability" it really depends on the recipient/recipient's family.... as long as there is a willing (and patient?) adult to do most of the work as kids won't be able to do this themselves, it's a wonderful gift! But if not, they might not enjoy this as much. ## Frequently Bought Together - NATIONAL GEOGRAPHIC Break Open 10 Premium Geodes – Includes Goggles and 2 Display Stands - Great STEM Science Kit, Geology Gift for Kids, Break Your Own Geodes with Crystals, Toys for Boys and Girls - NATIONAL GEOGRAPHIC Rock Collection Box for Kids – 300+ Piece Gemstones and Crystals Set Includes Geodes and Real Crystals, Rocks and Minerals, Science Kit for Kids, A Geology Gift for Boys and Girls - NATIONAL GEOGRAPHIC Mega Gemstone Dig Kit – Dig Up 15 Real Gemstones and Crystals, Science Kit for Kids, Gem Digging Kit, Gift for Girls and Boys, Mining Kit, Rock Collection --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/258653630-blue-marble-national-geographic-break-open-10-premium-geodes-includes](https://www.desertcart.lk/products/258653630-blue-marble-national-geographic-break-open-10-premium-geodes-includes) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-07-07*
