4.0 out of 5 stars Natural geodes so expect some variation
By Wendy E. Stallings on February 4, 2017
These geodes are natural, not a manufactured product (and not cement as another reviewer claimed), so expect some variation. Because they are real, no one can look inside ahead of time and make sure all ten geodes will be spectacular when opened. I didn't get any with beautiful colored crystals inside, but most were hollow with interesting crystals. Only one was not quite hollow, but it had a swirl of pale blue agate inside of it, so we were pleased. My thirteen year old son and I used a regular old claw hammer and had no trouble opening any of them, although read the instructions carefully!! Some of them are actually pretty fragile and will dissolve into a pile of sand if you whack too hard to start. We also used a chisel with some of them to try to achieve an even split, as the instructions suggested. We did this outside on the pavement as it does make a small mess (easily swept away). I am only giving four stars instead of five because unless you have a portable vice (or are willing to pound geodes in your workshop), one person does have to hold the geode (and chisel) in place while the other person swings the hammer. It's inherently hazardous. I was the "holder" while my son wielded the hammer. Luckily, I still have all my fingers and some nice geodes to boot.

5.0 out of 5 stars Loved it!!!!
By Brenda Wilhelm on April 16, 2017
These geodes were so cool! We got this kit for my son on his 11th birthday and he was not dissapointed in the least! He easily smashed most of them with a hammer. Just 2 of the bigger ones required a chisel and a hammer. They are beautiful! We didn't get a single dud!

5.0 out of 5 stars Great gift for kids!
By R. Miller on September 2, 2016
Purchased the geodes for my 7 year old's birthday. She absolutely loved breaking them open, but I was pretty excited about it too! We opened a few at a time and let the whole family and a few friends open one. I guess we got lucky and all of the rocks were actual geodes... no duds. Only one of the rocks was somewhat solid, but it still was filled with crystals. There were two different types of geodes in the kit. All of the crystals were either white or light gray-purple-ish. Very pleasantly surprised and pleased!

1.0 out of 5 stars Not like representation and disappointing!
Reviewed in the United Kingdom on February 15, 2020
Very disappointed with this product. The advertisement provides pictures of geodes of different colours, however they were are white and some had no centre, looking simply like sparkly stones. As these were bought for a 10 year olds birthday, he was very excited to crack each one open to be disappointed as they all appeared to be the same each time. Out of the whole box, he probably got 1 or 2 half decent geodes. Unfortunately even these do not look like the ones advertised. A very exciting gift but very disappointing when used. It’s heartbreaking when you see your child excited to then be let down as each one is cracked open.

Reviewed in the United Kingdom on July 23, 2020
Huge disappointment - the children were very excited to get this but were sadly let down. After much effort at following the “chisel scoring” recommended method we gave up to use brute force. The results explained the need, the geodes were mostly solid stone. Added disappointment that there was no verity of colour and the crystals (where they existed) were tiny. In include a photo of the opened geodes with the box in the background to show the difference between the “sale” photos and reality.
