This very pretty locket is antique circa 1900's, the Edwardian period. It's gold filled and stamped "F & B" amd "Pat." on the inside. The chain measures 15 inches long and about 3mm wide. The locket measures 1 1/4 inches in diameter and is about 6mm thick. The initials on the front are very ornate so and I think they read HET or HEF. The locket will hold two pictures but there is only one of the bezel type circles that hold the pictures in. The condition is very good. There are a few slight surface scratches and the clasp on the chain is bent a bit but works just fine.
