A Gorgeous Antique Diamond Wedding Ring Set 18K White Gold with Yellow Gold, Vintage Art Deco circa 1930's. This beautiful antique wedding ring set holds a fine white, very clean, old Euro cut diamond at its center measuring about 3.7mm in diameter and estimated to weigh about .20ct in diamond weight. There are an additional 9 diamonds in the set, for a total estimated .30ctw in diamonds for the set. The engagement ring and band are made of 18K white gold top with 14K yellow gold bottom, typical of high quality pieces of the Art Deco Era. Overall the set measures about 9/32 inch long by about 11/16 inch wide from side to side. Ring Size: about 4 1/4 (could be resized by your jeweler or ask me about using mine before shipping). The ring and band have been soldered together in the back, but if one wanted to have them separated, a jeweler could do this as well. This gorgeous set was acquired through an estate collection and is on lovely vintage condition.
