Olsen has been seen flashing the ring around New York City. The ring is reportedly vintage Cartier boasting a 4 carat European cut diamond surrounded by 16 calibre cut sapphires, and 1.5 carats of diamonds.
Olsen and Sarkozy got engaged after dating for 2 years and not without criticism. Sarkozy, who is the half-brother of former French President Nicolas Sarkozy, is 17 years Olsen's senior and has two teenage children from a previous marriage.
Olsen says that rather than listening to the criticism, it's best to "focus on what's in front of you."
