I recently purchased this set of 18 polished and unpolished stones from Battat at a Tuesday Morning store. I’ve checked online, and unfortunately I can’t seem to find anyone selling this set online. But fortunately, if you can find it at a Tuesday Morning store, you’ll pay 1/2 price for it.
What I love about it is that you can see what the stones look when they are polished and when they are in their natural form. It also came with a stone identification guide as well.
My five year old is really fascinated by the collection and will spend a lot of time looking at them.

Here’s a great website called Rock Hound Kids for kids who love rocks, minerals, fossils and geology.
