Sapientia Ring

This incredible ring recreates an ingenious ancient design for an adjustable ring! The original was found in the area of ancient Parthia, and dates from the first to the second century AD. The two side terminations of the original ring could slide closed (or become nearer to one another) to make the ring larger, or could slide open (or farther apart from one another) to make the ring smaller. 

"Sapientia" is Latin for "wisdom."
