One round diamond centers the face, with four smaller diamonds surrounding it, all set on a red colored stone. Additional diamonds appear around the bezel setting, as well as on the outer perimeter, with “PATRIOTS AFC CHAMPIONS” around the set stone. As this is a prototype, the size 10 1/2 ring is blank on both shanks. The Patriots defeated the Miami Dolphins, 31-14, to win the AFC title. This ring comes with the consignor's purchase LOA and a Balfour ring bag.
