It is the Michigan state stone. Found on our beaches. looks different when wet so hard to find, sometimes. It is a fossil colonial coral formed in the warm waters. They can be polished up and made into jewelry, they are carved into beautiful art objects. I have found several in the sand that are already polished and ready to use. I put clear nail polish on them so they shine as if wet all the time. They are just fun to look for. And find.
