A Gorgeous, Enchanting Antique Wedding Ring with Natural Blue Zircon, Vintage Art Deco Period c.1930 in Ornate White and Yellow 14K and 18K Gold Setting. This vintage wedding ring is quite special and holds a genuine blue zircon gemstone at its center measuring about 5mm in diameter. Zircon was often used in place of diamonds as the sparkle and life that zircon gives has a similar quality to diamond. The setting is made of ornate yellow gold with floral details and prong work done in white gold and is made of solid 14K and 18K Gold (marked 14K and 18K inside the shank). Overall the ring measures about 5/16 inch long by about 3/4 inch wide and is in lovely vintage condition. Ring Size: about 6 1/4 (could be resized easily by your jeweler or ask me about using mine before shipping).
