Dan&Darci Break Your Own Geodes - Hollow White Moroccan 1" - 2.5" Large, Medium, Small Geode for Kids - Science Kits for Kid Ages 8-12, 8-10, 12-14 Age - Discovery Toys Gifts

I have actually bought these twice! The first time, for a girl's trip. And the second time for adult easter baskets! I will likely buy them again for the next appropriate opportunity. Great durable quality, value for the price, and they were so much fun!

Great selection of geodes. Had lots of fun breaking them open to seeing what was inside.

Most were hollow and easy to open. I have used kits like this before and these were by far the best. All geodes contained sparkling crystals. Some crystals were clear like glass!

My son's girlfriend gave him one of these and when my 10yo daughter saw it she immediately asked if I could buy some. She loves sparkles and wanted to decorate her room with a bunch of pieces. I found this set of 25, and they are the best price I found. As shown in my 1st photo, most of them are pretty small. There are only 1 or 2 i would consider "large" and that's only in comparison to the rest of them. The majority are small, and are genuinely small! I haven't cracked a small one yet but I'm afraid I won't get any good pieces from them. Will update after I do. I cracked a large one and a medium sized one to get the pieces shown in my other photos. The 3 plastic display stands are just cheap little things, but they definitely help of you want to show off any pieces. The only pieces you can use on those will come from the largest rocks. Even the medium rock pieces were too small for the stands. The instructions tell you to either use a hammer, or to place in a sock and hit it on a hard surface. I couldn't crack it with a hammer at first at all. I put them inside an old sock (important because it WILL destroy the sock!) and then hit it with the hammer while inside the sock. That finally worked. It also keeps the tiny pieces from flying all over, and keeps all the pieces together so they are easier to pick up. The rocks themselves are ugly on the outside, but the crystals are the part that matters. Lol. The crystals are all clear on these. They are naturally formed in different sizes inside, so there are some areas with teeny tiny crystals that look a bit like crackle glass, and some areas with larger crystals. This is a fun project to do with children! My daughter is going to have many beautiful, sparkly crystals to decorate with! And it's cool to get to open the sock and see what you get with different rocks. I recommend this with parental supervision and help! Safety first!

My 7 year old loved it! The cloth bag it came with was very helpful to cut down on the mess factor. All the rocks were geos and we had no duds! Would be a fantastic birthday gift (we bought a few extra to have on hand for future birthday party invites.) great value for money!

I didn't read the description very well, so I didn't realize they were all going to be the same color. Regardless they turned out beautiful! I bought them for a date night idea with my boyfriend. He had never cracked one open before and on our last trip we bought duds so I was hopeful for him to break some this time. He did think it was cool, but lack of color got old sadly. I read online you can dye them so I'm going to try that. If it works, this gift give even more gift value and variety. The sizes were nice. Not too big, and not too small. Cracking them open left about the same size end results. I had purchased 2 at the time, but he said he'd random give it to his little sister for Christmas. *If the dye works I'll post a picture 👍

These are fun to break but they’re also almost all white inside so be aware of that

These were a huge hit with my kids! They broke open well, and definitely came with a good variety of sizes to choose from!

Purchased for my son’s geology themed birthday party. The boys had so much fun smashing them open with hammers and marveled at the beautiful geodes inside. They are now proudly displayed in my son’s desk.

Wonderful! Amazing and loved gift

I purchase this for my 8 years old grandson for Christmas which he asked for it. I have no idea what it was but according to my son, this is a very popular game at school. And at the same time they can learn about gem stones.

Bought for a science birthday party. Good quality. Every rock looked amazing inside.

Purchased as a gift for our 6 year old, along with some safety glasses and a claw hammer. He is THRILLED every time we take them out for him to bust. The box has enough that we grab a handful every time. The kid now has a big bag of "diamonds" that he thinks he's going to sell one day. Very cute. Will buy again.
