This is a women's Christian high school academy and yes the age would be correct. However, a keeper not. We (my wife) has been in contact with the family (son and daughter) for the owner died in 1993. Her husband is still alive, but may not be in the right mindset to receive the ring. So we are awaiting their decision as to the son or the daughter the ring goes back to.
Looks like some very nice Art Deco styling. A truly beautiful class ring. When it does go back make sure you add a follow up story.
