This is a  gents sterling silver vintage South Shore High School class ring from Chicago. Our store purchased this ring directly from Kinney company some time in the 1960's-1970's. The ring is new old stock ( no previous owner ). The ring is 20mm by 20mm on top with a blue synthetic center stone and is a size 8.5 and is 12.5 grams. A wonderful and unique treasure from the past! available in sizes 7 , 7.5 , 8, 8.5 , and 11.

        Note: This ring is not sizeable because the silver is coated in a metal that is possibly nickle.
