Amethyst Crystal Growing Kit Grow Purple Crystals With National Geographic

Super nice and very good four stars because takes a lot of accuracy and time and is a little expensive

Very disappointing experience as there was no crystal even after two weeks! We were given a faulty and sub-standard product.

Impresionante - funciono de maravilla. Lo unico es que despues de hacer el cristal, hay que guardarlo en un sition donde no le de el sol para que mantenga su color. Pero de verdad era genial!

I bought this kit for a Christmas present for my 7 year old grandson so I can't write a review about how well it works yet. All I can say is that I was happy with the speedy delivery as it arrived a day earlier than expected and the box and all its contents were intact. I bought a blue crystal growing kit for my grandson last year and he really enjoyed watching the crystal grow, it was he who asked me if I would buy him a purple one for Christmas this year. I have no doubt that he will enjoy watching this crystal grow also.

Did this yesterday with my little daughter and the crystals are already covering the rock. Can't wait till next week when we can empty the glass and see em. Just use ro water from a fish shop as it's better quality water.

Didn’t work despite following up the instructions

Super kit pour faire pousser un cristal. Ma fille de 9 ans a été ravie, et nous sommes tous bluffés par le resultat. 7 jours après avoir suivi les indications nous avons du casser le bocal dans lequel le cristal avait poussé afin de sortir le cristal :) Vraiment à recommander pour tous les petits passionnés de pierres précieuses.
