This is another of my modernist designer silver rings from the 1970s.
This one is British in origin - and has a London hallmark for the date 1978.
There is also a stamped monogram CD, but I have been as yet unable to identify the maker.
This is a fine "one-off" piece of vintage jewellery - with four stepped "fingers" - one is open at the end. The inside of the shank is polished but the exterior has a textured finish. It is a very sculptural piece.
Very stylish with a contemporary minimalistic feel to the design.
It is a nice larger size too - being UK ring size Q
