NATIONAL GEOGRAPHIC Break Open 10 Premium Geodes – Includes Goggles and Display Stands - Great STEM Science Kit, Geology Gift for Kids, Geode Crystals, Toys for Boys and Girls

Absolutely brilliant. Realy impressive and genuine geodes. My son is seriously impressed with this and hes been left with some really good crystals for display.

After mixed reviews I was undecided whether to buy this or not. However, my granddaughter absolutely loved it. Yes, most of the crystals were white but the exciting part was breaking them open. My granddaughter had a really good try at breaking them open but adult help is definitely required.

Very impressed so far! Obviously my so. Wanted to open the largest one and also a darker colour than the rest. I had read the previous reviews where people were disappointed, so I made sure he knew there was a possibility they might be all white. I think they are beautiful whatever colour and the rest are going in his party bags as party favours. 4stars instead of 5 for the size variations some are tiny.

Excellent. Very nice. Interesting.

Good activity pack for a rainy day and for a child that enjoys geology. My feedback for this product is that the geodes are mostly white quartz with some variations in thickness. Some were too hard to open with a hammer and chisel like the instructions suggest, and my husband had to resort to cutting them open with an angle grinder (highly recommend - saves a lot of effort!). My son was delighted with the crystals inside but I felt they were a bit underwhelming compared to what is presented on the packet. For the price, it’s cheaper than going to a specialist shop and opening the rocks did bring lots of entertainment.

Thank you. We bought it as a gift for 10 years old girl. And she was very exited, the fems are heavy and brilliant color

Four varying sized rocks and there are goggles for eye safety. My great grandson will love this. I had to check with Mum and Dad to make sure they had tools to crack them open first before I bought it. I'm more than happy with it.

The box has not been opened as it is a present for my grandson so star rating doesn't really apply. Just to say, be aware of the weight. It says 0.84 kilograms. It's not! It's 2.00 kilograms. Hope it's not going to make my case over-weight.

Padrisimoooo mi hijo se divirtió muchísimo abriendolas!

It was a great gift idea

Per essere un gioco di National geografica e una delusione, ci vogliono attrezzi adatti e una forza disumana per staccare le pietre

Great set but be warned, these are quite hard to open. With the regular hammer, I probably had to hit it for a good 20min! I guess it attests to their authenticity

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.
