ORNATE DESIGN & DECORATION-1960'S POISON RING WITH HINGED OPEN COMPARTMENT-PATENT DATE FOR UNIQUE DEVICE FOR RING SIZE ADJUSTMENT This ring is truly a unique piece of jewelry.

The ring/compartment setting is 3/4" deep. It appears the inside compartment of the ring is enameled white. The ring shank is slightly squared off. This is w the patent comes in. You can pull on the back piece to adjust the size of the ring; unique invention. Stamped on the inside of the ring is "Pat. 2,961,855"; dating around the early 1960's.
