Martha Wayne's pearl necklace was a pearl necklace belonging to Martha Wayne.
After leaving a popular musical, the Wayne family was mugged, with the mugger asking for Martha's necklace. She ripped it off of her neck in an attempt to give it to him, with several of the pearls falling off. A duplicate necklace was later placed in Mario Pepper's apartment, to frame him.
