Silver Shell spoon ring. Adjustible. Fun fact! If you visit an Italian restuarant, that's old school and they have the original utensils. You will probably see this. I found this at Barbarescos and I showed this ring to one of the waiters. Then the waiter told one of the owners, and he couldn't believe it. Long story short, it might be there silverwear from the 1920's, the ring is dated 1974 because of the estate sale of where it came from. This is still an unsolved mystery.
