This unusual ring is vintage circa 1960s/70s. It is fashioned from sterling silver and is stamped on the inside "sterling". Each of the four pieces that go into making up the whole of this ring, measure 11 X 3mm wide and the ring size is 7 1/2. The condition is very good with just the usual surface scratches. There is one tiny dark spot on one side which would not polish out with silver polish. It weighs 4.6 grams.
