These lovely bags are 200gms of B grade tumble stones with the odd point thrown in.
Brilliant for kids - you could suggest they make a mandala or grid out of their bag of treasures and write a wish for the middle.
NB PLEASE CHECK THE CRYSTALS FOR ANY SHARP EDGES BEFORE GIVING TO KIDS AS THERE are SOMETIMES LITTLE CRYSTAL POINTS ETC. I check all the tumbles so they should be fine but best to double check.
Or give them to your older kids with either a Crystal Bible Book or the internet and ask them how many they can name.
Or they are equally as enjoyable just to play with, I have seen many kids spend hours entertaining themselves with a bag like this (though do be prepared to find them in your underwear drawer - in the fridge and all manner of other imaginative places!).
And lastly of course - why should kids have all the fun - it's a great way to learn about the different crystals - one at a time you can put into your search engine "green crystal tumble stone" click "images" at the top of the page and see if you can find them. I'm afraid these don't come with a list but they will all be one of the ones in the drop down properties list on the home page.
Each bag is unique, the ones in the photos are examples - you may get one of those, I have made an effort to ensure that each one has a good variety of colours. Enjoy!
NB These are not suitable for small children or kids who like to put things in their mouths.
