This is one of the keys from a Saxophone from the 1920's. Don't worry, no working instruments were harmed in the production of this piece! The sax was in sad shape, and per the experts would have cost a fortune to restore to working shape. The mother of pearl key was carefully sawed off the sax, sanded and filed down, and added to a vintage gold tone chain.
This is a petite necklace any sax player or admirer would love to own.
