Vintage Sterling Silver Ring with Dangling Bells Balls size 7-1/2, unmarked

Cool silver tone ring, unmarked, size 7-1/2. I've had this ring over 30 years and it was bought as vintage then, otherwise the age is unknown, Could be 1960s to 1980s, maybe older
It is unmarked, but it really seems like sterling silver, it has not been tested. There are 9 bells or balls on the top. They make just a tiny jingle when you shake the ring.
Very good condition. Tarnished and aged, needs to be cleaned. Some of the bells have dents, some wear to the finish on the inside of the ring.
