Mary-Kate Olsen and Olivier Sarkozy
Since abandoning their acting careers and focusing on their highly successful clothing line, the Olsen twins have kept to themselves. However, Mary-Kate’s massive engagement ring couldn’t be hidden from the cameras.

The French banker proposed with a glamorous Cartier ring, a European-cut 4-carat diamond surrounded by sixteen sapphires. The vintage ring dates back to 1953. It’s true what they say – French people have style.
