Sean and Catherine
Engagement announced: March 2013
Sean, who was second runner-up on Emily Maynard's season of The Bachelorette, proposed to graphic designer Catherine Giudici with this 3.15 carat, platinum cushion-cut diamond ring surrounded by 164 smaller round diamonds. The vintage-inspired ring—and the season—was a hit, and the pair are reportedly planning a wedding to be televised on ABC.
