This is the jewelry set that was worn by Sarah Wayne Callies' stunt double, Corry Glass, in the Season 5 episode "The Liar" (5.03). Sara is also wearing this necklace in many episodes, so it might have been used in those episodes too. It consists of a pair of small white earrings and a very delicate necklace. It also came with the plastic bag from the wardrobe department.
