National Geographic Gemstone Dig Kit - Fascinating Gem Excavation Kits for Kids with Authentic Amethyst, Quartz and Tiger's Eye | STEM Educational Science Kits Gifts for 8+ Year Old Boys and Girls

Lots of fun and instant gratification for the kids as the crystals started to grow within hours. After 2 days it was a fully grown crystal garden.

They are really great. Easy to do and grew a lot of chrystals. We left them overnight and the trees look lovely now.

Bought for my 10 year old. She loved doing it and watching them grow was really cool. You can’t keep them afterwards though as they aren’t solid but a nice crafty thing to do together!

The kids enjoyed colouring them in and seeing the crystals the next morning. The card was flimsy and easily bent on assembly. It was difficult to pour the solution on from the packet without it going everywhere, and the crystals didn't colour anything like as well as in the picture. They also fell apart very quickly and I've no idea if the crystal dust is safe to inhale or not so they were quickly binned, which is disappointing. We won't be buying more.Considering this is National Geographic branded, such a short lived product and the large amount of plastic involved in packaging and pens (which pretty much ran out during the colouring process) is not great.

Item as described worked really well, kids loved it

Terrible product, nothing like the photos. When you pour the gel over the cardboard tree the cardboard itself goes to mush, the markers are terrible quality and 2 of them were completely dry. The crystals grow to nowhere near the the trees in the photo. Very disappointed 7 year old! Don't waste your money in this!

Nice items for teaching the kids. However, the card tree parts were slightly broken in the box so had to be extra careful not to fully break them in colouring. Some of the felt colours were actually out of ink and ran dry quickly, and not enough liquid to give anywhere near the same representation on the front of the pack.

Very disappointed, the pencil didn’t work well. So I used other ones. It grows not well like the picture.But what I really loved is that there is a book with information about crystals, it is very interesting.

Inte lika spännande som antyds.Gipset sprätter iväg, dammar och det blir riktigt smutsigt.Denna bör man använda utomhus…

Los minerales son pequeños y tardan unos 5 min en encontrarlos si no es menos, pero como regalo original está bien, bien presentado y con el respaldo de la marca.

A perfect gift for any kid. Its a great way to introduce them to science while playing and customizing their own crystal tree

vraiment super!! ma fille a 4 ans elle a adorée!! ( maman aussi ) 😊

Facile à utiliser et résultat très sympa ! On regrette seulement que le liquide à cristaux soit si difficile à verser avec précision (on le remarque sur le second arbre, qui est plus clairsemé que le premier). Pour une meilleure utilisation et une meilleure couvrance, il aurait fallu inclure une pipette dans le kit.. N'essayez pas non plus de colorier les arbres de manière trop "artistique", sinon toutes les couleurs ne seront pas visibles sur le résultat final. À part ça, c'est vraiment super de voir les cristaux se former et les arbres se couvrir ! Le résultat est super beau !
