"Bruce's mom was killed for that necklace."
Kate Kane on the importance of Martha Wayne's necklace[src]

A pearl necklace was formerly owned by Martha Wayne. It now functions as an entrance into an elevator at Wayne Enterprises which leads to the Batcave.


Martha Wayne wore the pearl necklace on the night of her death when a mugger assaulted her, stole the jewelry, and murdered both Martha and her her husband.

After the couple's murder, their son, Bruce Wayne, searched for the necklace on the street for years, eventually buying it back at an auction.[1] Bruce kept the necklace in his office inside a square pyramid-shaped glass container that functioned as an entrance into an elevator that lead to the Batcave.[2]

In fall 2018, Bruce's cousin, Kate Kane, agreed to have the pearl necklace up for display at the Museum of Antiquities to represent the role model Martha was to all women in Gotham. However, a jewel thief named Magpie broke into Wayne Tower and stole the necklace. Kate, as Batwoman, found and retrieved the pearl necklace, returning it to its glass container. She then managed to foil Magpie's plan to steal all the jeweled artifacts in the museum by using a bomb, disguised as the pearl necklace, as a diversion.[1]

Behind the scenes

  • In the DC comics, Martha Wayne's pearl necklace is the iconic reason she and her husband were killed; the family was walking home from a night out at the opera when a mugger known as "Joe Chill" assaulted them, demanding the necklace and fatally shooting the couple after Thomas tried to fight back.
