A Stunning Antique Champagne Diamond Wedding Ring, 18K White Gold Filigree Setting, Approximate 1/2 Carat Diamond, circa 1920. This gorgeous classic antique diamond ring holds a sparkling antique faceted diamond at center measuring about 5.2mm in diameter and is estimated at about 1/2 carat in diamond weight. The diamond has a bit of a champagne color, making this quite a unique piece. The faceting of the diamond are somewhere between an old Euro Cut and a Transition Cut and they catch the light beautifully. There is a chip near one of the prongs, however this stone is original to the setting and this is not something that you are going to notice unless you are looking for it. The setting is exceptionally beautiful 18K white gold filigree openwork. The setting has crisp detail and is in beautiful condition. Overall the ring measures about 5/16 inch long by about 13/16 inch wide from side to side. Ring Size: about 8 3/4 (could be resized by your jeweler or ask me about using mine before shipping). This ring was acquired through an estate collection and dates to the Art Deco period, circa 1920.
