JA-RU Real Diamond Mine Gemstone Dig Kit (12 Packs) Mystery Rock, Minerals, and Gems for Kids | Break Your Own Geodes and a Chance to Get 1 Real Diamond | Party Favors for Kids Goodie Bags. 4630-12

It is what it says, different types of stones. There are diamonds (cough). The diamonds are small shards. Mostly. You tuber that have taken them to jewelers to have them appraised found them to be worth about 3.00. My son was still very happy to have a real diamond so they are worth it.

My granddaughter (age7) is always excited to mine her own gems!

I ordered two of these for my 11 yr old nephew. He had great fun carving away at them to find his prize. He didnt get the diamond chip in either one but did get two nice specimens.Good value for the price. Fun afternoon endeavor for 11 year old child. Two thumbs up!

This is what I got, not quite what the picture looks like... Very disappointed.

My 7 year old had a lot of fun with this. It can be messy, especially if adding water. It was a hit in our house.

Had to use a hammer to actually break through to the gem/stone

You will have to put a little elbow grease into cracking it open but it’s cool to reveal

The only thing I don't like is that most of the time the treasure inside is at the bottom of the diamond and takes about 3 seconds to find and remove. The kids don't seem to mind and they ask for them every year.
