"The white gold Seahawks Super Bowl XLVIII championship ring features a three-dimensional Seahawks logo of 64 round diamonds with a vibrant emerald hue tsavorite eye. The iconic logo is outlined in blue and is framed by 12 diamonds. The Vince Lombardi Trophy, comprised of one marquis diamond, stands in the background amongst a sea of 107 round diamonds with a border reading 'WORLD CHAMPIONS.' Forty blue sapphires surround the ring top flanked by two “12” flags."
According to the team, the ring band also features 12 feathers with the phrases "Leave no doubt," "24/7," "SEA 43 - DEN 8" and "What's Next?" engraved inside each ring.
The rings were unveiled in a private ceremony that included a performance by Usher.
