An Exquisite Platinum Antique Diamond Wedding Ring, Vintage Edwardian - Art Deco Period, circa 1920 with Exceptional Detail. This gorgeous antique wedding ring holds a fine white diamond in the center, clean and clear, and is estimated at about 4.4mm in diameter or about 1/3ct in diamond weight. The sparkling diamond is set in one of the most fine filigree settings that I have had over the years. The setting is composed of fine platinum and has intricate filigree openwork detailing and a bit of engraving on the sides. The ring overall measures about 11/32 inch long by about 11/16 inch wide from side to side. Ring Size: about 4 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 is estimated to date circa 1920. The ring is in exceptional vintage condition for an original antique piece of this age.
