Price is equal to product.
Purchased this for my child turning 12, home schooling, made an easy & educational experience. Child has more fun digging the clay enclosure, than listening to it bubble(scream) for help in water. Even 3 year old was able to enjoy & join the activity. Stones are small side but overall acceptable.

Perfect for a fun activity!
As a geologist, I love giving family these little diggy-type activies during the holidays to unearth rocks and minerals. This one has been my favorite one I've ever done! The rocks inside were nicely polished, rather than cut into ugly squares, and they actually had some very interesting rock types than even I got excited about getting! This is definitely the perfect activity to give the people around you who need more digging for rocks in their lives - geologists included! I do have a couple of nitpicks, though, as someone who has done a lot of these digging-type things over the years. Firstly, the tools provided are very minimal - some kits will provide move shovel-type tools, but this one only has a tiny pick that is more suited to a child's hand size than an adult's - so if you have big hands, beware for cramps incoming! (I realize these kits are usually for children, so this is a minor nitpick, haha). The main problem with this one is actually the guide - the rock identification guide in my box actually had the Sodalite and Lapis Lazuli identification photos mixed up. The rocks also don't match the photos very well in general, so for the children (or adults) in your life who are interested in rock identification, this part may be a little difficult. To non-geologists, though, it might not matter what the actual ID of the rock is! But I had to identify them all for everyone, since the guide photos were not so forthcoming. Overall though, these kits were actually my favorite I've ever gotten! I'll definitely be getting them again next year, too!

Fun and educational
I purchased this set for my 4 yr old grandson and we worked on digging out the gemstones and rocks together. He would attempt to identify each stone and we would discuss which of the stones had similarities to the one we uncovered, then read the information card for what we decided through careful deliberation was the correct stone. Hours of enjoyment and a great project to do together. I would have loved it if the stones were slightly bigger making them easier to identify and also to keep track of. Including a small drawstring bag to keep them in would also have been great. He was happy with the collection, enjoyed organizing the stones with the large chart included in the set and we talked about our favorites and the qualities of each stone numerous times. Later he used them as a load to be moved about using a small toy loader and dump truck.

Fun Quality Product!
My 9yr old has become interested in rocks. Got this as a Christmas gift and it was perfect! Me and my daughter would look at the big chart that comes in the box and guess which gem we thought would be dug out each time. She then dropped a block into a cup of warm water for a minute, pulled it out, and chipped away at it. I was impressed with the quality of everything included in the kit. The cards are a good thickness and print. The clay was not too hard or soft. The 12 picks a sturdy plastic with brushes on the end. The rocks included are an appropriate small size, all intact with no chips, and good coloring. They match the cards. This is an item I liked enough to add to my Birthday Present Idea list for my kid's friends.

Fun, but...
I was sooo excited for these they were an activity for the kids to do. The kids LOVED them. It says soak in water for 5 minutes I didn’t know that or didn’t read that before hand so just FYI. However the part that was disappointing was the rocks were very small less than 1” and there was only 1 tiny gemstone in each. The really disappointing part was that they weren’t even in the middle most of them sat right on the top of you scratched the surface you found the rock so besides waiting for them to soak the kids didn’t even have to dig for them. The packaging was good they came with tools and information cards. They were individually shrink wrapped which was nice. All in all we did enjoy them.

Todo un éxito
Compramos estos bloques para un proyecto del colegio de mi hija que trataba sobre arqueología y excavaciones. Al finalizar el proyecto los niños de la clase tenían que excavar en su bloque buscando la piedra preciosa... Fue todo un éxito. No son gran cosa, pero son perfectos para usar como detalles para juegos, búsquedas del tesoro, juego de cumpleaños o como en nuestro caso, para ser usados como final de un proyecto en clase. El mineral que entra está pulido, es una piedra no muy grande, pero suficiente y unos son más llamativos que otros. Vienen bien explicados, con tartejas informativas de cada mineral. Los bloques no son muy duros, por lo que se extrae bien el contenido, pero si los peques no pueden rasparlos bien, basta con mojarlos un poquito para que se ablanden. Lo volvería a comprar.

A fun way to learn about Gemstones giving the kids a chance to feel like archaeologists!
Brought for my daughter, she absolutely loved it! She roped in her younger brother to be her assistant. Occasionally an extra gemstone may be found in a block, which is a good bonus!
