Margot Robbie turned heads when she arrived at the Oscars Sunday. The 24-year-old Australian actress walked the red carpet in a stunning black Saint Laurent dress with a plunging neckline. Robbie, who is a presenter at the 87th Academy Awards, paired the gorgeous gown with matte red lips and a jaw-dropping statement necklace from Van Cleef & Arpels.

According to Robbie, the jewelry was created for the Duchess of Windsor “or something” in the 1930s.

“The necklace is worth more than my life,” she joked on the red carpet with E! “I better not lose it.”

Besides presenting at the award show, Margot Robbie can be seen in the upcoming movie “Focus.” The actress stars alongside Will Smith in what she describes as a “killer love story.” The film hits theaters on Feb. 27.
