Break Your Own Geodes – 3 to 4 Premium Natural Geodes (3.5"-4.5") - Great STEM Activity for Kids Ages 8-12, 8-10, 12-14 - XL

I bought these particular geodes because I wanted to hide a couple inside plastic Easter eggs this year and introduce my young granddaughter to a bit of geology via crystals. I did read descriptions and reviews for many different geode sets on Amazon before deciding on this particular set with high hopes--but I also knew from experience with buying geodes in shops that the ratio is usually a very few really open crystal-filled geodes to many more with solid interiors/limited if any crystal formation. So...I only hid 4 geodes inside of the plastic eggs, one of which was the only geode in the whole set that arrived slightly cracked and that was a good thing because I could already see some crystal formation inside (so at least 1 would have crystals). Imagine MY surprise when it turned out that ALL 4 of the geodes broke open full of crystals, all 4 of them having open-space crystal-lined interiors and 2 of them actually cracked open into amazingly neat half-domes (I used a small short hammer sold on Amazon, heavy-head & sturdy grip, useful for small spaces: placed the geodes on patio pavemnt and we gave each geode a few steady taps and then a heavier hit or two). 100% success and i was as amazed as my granddaughter was! I'll be saving the rest of the geodes for future activity but I now have very high hopes for the rest because the 4 geodes that I chose for Easter use were the 4 SMALLEST of the whole set (about 1 1/2 inches) so that they fit easily inside the larger plastic eggs and weren't too heavy/they were light enough that the plastic egg stayed closed even when rolling around in her basket as she collected other eggs). I couldn't be happier with this set and highly recommend.

Great for kids! Every once in a while I’ll throw some in the yard and tell the kids there was a meteor shower last night and to go look for the special rocks. They have a blast and these are relatively inexpensive to buy.

Some really enjoyed them

I'm an adult but I absolutely loved this! For smaller children supervision is required though. Also, it's a little messy so maybe do it outside.

These geodes are beautiful and fun for all ages!

Fun

These geodes came in, and at first i was hesitant because they didnt ship the way i expected. They were just 20 round ish rocks in a bags packed inside an amazon box. But i cracked the first geode and was absolutely stunned with how amazingly beautiful, crisp, and clean the crystals were. The pictures dont do it any justice. If you love crystals and want a quality set for the fun of it at an affordable price this is definitely the set for you. I plan on getting the large ones next.
