Break Open 2 Jumbo Geodes– Break Your Own Large Geode with Crystals, Earth Science Kit for Kids to Learn Geology, Gifts for Rock Collectors, Cool Rocks for Boys and Girls

Both had creator in them very happy

The product detail page says the geodes are about the size of a baseball so I placed them next to one and took pictures of both geodes.

My 7 year old and I pounded away with a mallet but could not break it. We needed help.Once broken, the inside is beautiful! Lovely white sparkly crystals.I’ve given a few as gifts and had great feedback.

I wanna start by saying At first I rated them a 2 star. Because the geodes were hollow, but they were quick to respond and they definitely made up for it. They sent us 2 new Geo's plus a few extra goodies. My kids went from disappointed to extremely happy.They went over and beyond to make things right. They were quick and efficient. will definitely be ordering from them again!!!

Interesting but... not for a child under 10 to try and open. An adult had a struggle opening one of these rocks. Also- these were the large ones? I'd hate to see the small ones!Nope.

I bought these “geodes” for my nephew as a Christmas gift without reading reviews first and I was embarrassed as everyone agreed how horrible these rocks were. They were impossible to break, the grown men had to open them and once they opened they were just normal rocks. Wish I would have taken pictures.Update: This company reached out to me and wanted to make it right. Such amazing customer service. They said they back their products and want their customers to have a great experience. 5 star service for sure!

We bought 1 box of two large (hardball size) geodes. One had excellent quartz crystals inside. The other was solid. The company promises to replace geodes that are solid, so we sent a photo of the solid one and asked for a replacement. We expected to get only one geode back, but the company promptly sent a box of two. Both of those were good, one with quartz crystals and one with another mineral that we believe is calcite.We used a masonry blade on an angle grinder to open the geodes. We clamped the angle grinder in a hand screw and clamped that in a bench vise. We put some wood blocks under the blade to support the geodes while we cut them open. That worked very well. Much better than smashing them to smithereens with a hammer or even trying to use a chisel to open them. An alternative method would be to hold the geode in a clamp or vise and make a series of cuts around it with the angle grinder. That would be slower than our method because it would require continually releasing the clamp or vise, turning the geode, re-clamping, and then making another cut. You don't want to cut all the way through if you can avoid it because often (two out of the three we opened) the crystals inside stick well into the cavity and would be cut off if the blade went deeper into the geode than the thickness of the shell.

These were impossible to break. I didn’t even know it was possible they could be solid. My 2 kids and I spent forever trying to break these open, damaging tools, making a crazy mess. Had to wait for my iron working husband to come home to smash them with a hammer which took 10 or so good blows while sharp pieces of rock were flying everywhere. Kids couldn’t be near it to experience it. Then when they did break open they were solid and looked like any other white rock in their minds. Such a waste. If you sell a product like this for so much money, I expect a real geode. If you advertise as a kids product, make sure a kid can actually do it. They were so disappointed they couldn’t be the ones to break them. Took all the fun out of it. Then to have them open and look like a regular white rock. No thanks. Wasn’t going to share a picture since they weren’t worth it. But noticed a white rock my daughter collected so had to show a comparison. 2 in the back are the “geode” from this pack. The 1 in the front is a random rock she found outside.

Good size and good quality geodes. I have found this with all Dr Cool geode products. I have bought many now. I would recommend these.

The media could not be loaded.  Video to show geode size and sparkle. Both are beautiful and I will buy again!!!Love them...Update: did buy again, sadly this time 1 if the geodes was actually 3 tiny geodes and lots of clay :(Will reduce rating from 5 to 3 stars

C'est sympa, il a fallu que je donne un coup de main, il faut un vrai marteau et un vrai burin pour obtenir quelque chose de propre.2 garçons contents.

En nuestro caso las dos geodas salieron iguales, de color blanco. Muy chulo para los niños. Sí que cuestan un poco de abrir, pero con paciencia se abren bien.

Complessivamente questa versione di geodi del Dr. Cool mi ha deluso.Infatti i geodi non sono più grandi di una palla da tennis...al massimo avranno (forse) una dimensione paragonabile ad una palla da tennis...ma le altre due dimensioni sono inferiori.Inoltre nella confezione, diversamente dal kit del Dr.Cool che contiene 4 geodi più piccoli (ma non di molto), non è presente altro se non i due geodi....quindi niente sacca in tela..niente lente...niente depliants.A questo punto, avendo lo stesso prezzo (quando li ho comprati io) consiglio il kit dei 4 geodi.
