5.0 out of 5 starsGreat kit
Reviewed in Australia on 26 December 2021
My son (11) had a great time smashing these geodes. We had to smash the heck out of them. We got several beautiful sparkly hollow ones and a few just pretty rocks. In terms of colour yes it would have been nice to get something other than white but you can’t see inside a rock so … 🤷‍♀️
My son loves them.

1.0 out of 5 starsSo disappointing!
Reviewed in Australia on 30 August 2020
Does not look anything like packaging! Extremely difficult to open, both adults tried and it took so many blows, sometimes they never opened because there was no opening on the inside just a ball of concrete and there is no way a kid could do it. Colours are crap, one purple one in the whole batch, the rest are white.

This was given as a gift. The advertising implies there are coloured geodes inside. Unfortunately all of them were white crystals just in different crystalline structures

Good sizes. All geodes are very white, only one is slightly coloured. Learning guide is a bit useless when all stones are quartz.

2.0 out of 5 stars Very disappointing - nothing like the picture.

I am very disappointed with these. I bought them as a Christmas present for my granddaughter. She was really excited when we opened the first one and found the crystal inside. Since then we have opened one every few days as a treat. However her excitement soon disappeared. Two of the geodes didn't contain any crystal at all and the others were all the same white colour, not different colours at all. In fact not one of them looked anywhere near as good as the illustrations on the box, they did not have the hollow inside so the crystals do not show up nearly as well. Both my granddaughter have ended up really disappointed in them and whilst I didn't expect them to be exactly the same as the illustration - I know they are natural products - I feel they don't even come near and I believe I have been misled and let down. I certainly would not recommend them to anyone else.

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.

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.

I am very disappointed with this product. The packaging is very misleading. There is a large picture of a hammer on the photo suggesting a hammer is included "break open 10 geodes" you say. I can move past the hammer, I should have read the text more carefully, the picture is misleading nevertheless. 7 of the geodes are the same. Not one of the geodes is colourful. On the box, it suggests you will receive a selection of colourful geodes. The leaflet inside goes into description about a variety of crystals but we were not blessed with receiving any of them. You must know what you are putting into the boxes. It cannot simply be random. If you are selecting 10 geodes from your stock, if your stock is 70% of the same geode, then you must know (and should tell customers and not mislead them with the packaging), that the child will receive the majority of that one geode. Perhaps you should run a competition like Wonka's Golden Ticket - find a colourful geode and all your dreams will come true.

A bit disappointed in this for the price as they didn’t break as good and well as said. Only a few pretty ones from the whole 10. All we’re the same colour box was misleading. Some geods were jsut rocks inside the ones that turned out good we’re very pretty but we’re from a rock cutter

3.0 out of 5 stars Good fun for 8 year old, especially if you manage expectations
Reviewed in the United Kingdom on 6 April 2022
Style Name: 10 Geodes KitVerified Purchase
The geodes were an ok size and we were able to break them open with a normal claw hammer, it's a little old school with a wooden handle which was nicer than the full metal/rubber grip hammer I had

There was some slight variation in the crystals from cloudy to clear, and in shape. I told my son that they'd all be the same so he was quite interested in the differences. It makes sense that they cannot test for colour.

Some were basically rocks, sadly it was the pink ones which had primed us to think they were special. These did have a different heft. Obviously whoever is selling these could devise a test for if they are crystal geodes or not using displacement/weight but they don't which is what drops the value for money.

There were enough that by the end my son was swinging that hammer like a pro and shattering them
