ESTATE 14K Solid Yellow Gold 8 Diamond MCM Designer Artistic Modern Atomic Ring. This is an authentic mid- century ring. It is not marked so I don’t know who the designer was. It tests as 14k gold and weights 7grams.The size is somewhere between 5.5 and 5.75. Band is flat in back and can easily be sized.I am not a jeweler so can’t grade the diamonds but each of the cat eye area’s holds 2 diamonds side by side and they appear to be of good quality. The black background is some sor...t of paint/enamel.The ring does show use/wear but that is to be expected! Please see photos as they are part of my description.I’m a reputable seller and stand behind my items. Bid with confidence
