Actress, Emmy Rossum, looked stunning in a matching suite of Piaget high jewelry as she arrived at the premiere of “Eugene Onegin” at the Dorothy Chandler Pavilion Saturday evening. Rossum, who currently stars in the acclaimed Showtime television series, “Shameless,” is a longtime friend of the Swiss jeweler.

For her night at the opera, she chose Piaget’s breathtaking Limelight Paris Couture necklace in white gold, set with 426 brilliant-cut diamonds and two pear-shaped emeralds, with a pair of white gold and diamond earrings.
