This antique engagement ring is a stunning example of Art Deco era jewelry. It has incredibly crisp milgrain detail and an openwork design, both hallmarks of rings of this time. The glittering center diamond weighs .31 carat. The ten (10) smaller diamonds surrounding it weigh a total of .22 carat. The shoulders of the ring have a repeated geometric design capped off by more milgrain and the back of the band has a smooth finish.
