This is a nice little resource for geology/gems/rocks. It has beautiful pictures of approximately 20-25 rock specimens that are flash cards.There are a few little lines of info. about each specimen on the cards. If your child likes rocks, gems, jewelry, this is a great resource. It can also be a useful tool for possibly identifying specimens that you have of your own. Very nice free resource, thank you!
