Customer reviews
We loved this! Bought and opened twice, beautiful crystals each time.
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.

Pleased what what we received
I’m pleased with the geodes we got in our box. I’ve had this 10-pack in my cart for a little while debating if I should pull the trigger or not after seeing some disappointed reviews. It seems a lot of people get either 10 boring clear quartz or a mix of 10 clear quartz geodes and nodules. I decided it’s only a $30 gamble so may as well. Ordered and it showed up 12 hours later. For 2 or 3 it took a while to bust through I’m assuming because two of them were nodules. The rest were relatively easy to break through with a heavy duty flat heat screw driver and a hammer. I also used a vise clamp to hold the geodes in place while I hammered away. Chipping little by little and rotating to try and split them in the middle worked fairly well. We received probably 50% clear quartz, however we also received the other half having some color. You could tell from the exterior if there was going to be some color inside, it’s pretty obvious once you crack a couple open to see the pattern. The pale beige, almost white, geodes are clear. The darker exteriors had some dark grays inside. One was darker exterior with a reddish hue and had some dark grays inside with some dark reddish flaking which was really nice. They’re not amazing, and I’m sure they’re overpriced for what they are, however I’m happy with what we received. I popped them in some floating display frames I got cheap on amazon and put them on a shelf that gets hit from the side with filtered natural light.

Great quality and variety for a great price!
My nephew loved this! He is curious little man and this was perfect for him. Not too messy, had a great variety of geodes that looked amazing under the National Geographic microscope we got him. Definitely an outside/patio activity since he has a baby sister we try to keep the noise down for but overall 10/10.. In his words "these are amazing". The adults were even entertained!
