Does Georgia Have A State Rock? If So, What Is It?
Georgia does not have a state rock but a gem and mineral
Not that I know of but if they did, It would probably be a common rock.
The state of Georgia does not have a state rock per sei. The state gem is quartz, and the state mineral is staurolite. Both of which are as close to the state rock as you will find.
