Four large football shaped stones on top of this 10 karat ring, with “San Francisco Forty Niners…World Champions” around. “Montana” on one shank above 49ers helmet, and “Back To Back…Team Of The Decade” on the other. This prototype has faux diamonds, and is a style that was not used by the Niners, making this a one-of-a-kind. Size is 9.5 and is Near Mint. A beauty.
