What a charming piece this is! This well ring stands atop a lovely chunky band which perfectly counters the weight of the setting, stopping it from rotating too much on your finger. 
 
Wells are said to be a symbol for Community. In ancient times the Well was both symbolically, and often literally, located at the center of the Community. From the Well, the community drew water, the basic sustenance for life.
