A quick fun learning project, these unassuming stones hold a secret inside: crystals! No two are the same and each is a little bit different. Each stone is approximately 1.75 in circumference and very light.
These stones come whole and ready for you to break on your own. It's a new surprise every time you break one and you will be the very first person to see the beautiful crystals inside. Just make sure you keep them in a bag and use a hammer. Gently tap, no need to smash, you can always tap harder if need be. Great for budding archaeologists 5 and up!
