It was a birthday gift for six year old girl and she was so excited. I think it was a good choice cause it gave her experience with crystals how to make them and how to paint them and how to make jewelry. Well worth the money.

Educational, cute and fun.

I got the Youverse crystal growing, jewelry stem activity kit for my kids aged 11 and 5. It was very easy for my 11 year old to master, 5 year old needed a little assistance. From beginning to end, it took about 30 hours. They loved being able to check every few hours to see the "crystals" growing The results are some beautiful charms they can wear.
