Catwoman necklace from show?

I found an image on the National Museum of American history web page that claims this necklace was donated by Julie Newmar and was worn on the tv show but I dont remember it. Can anyone confirm or name the episode?

It’s not from the show, but she wore it in later photoshoots with a different catsuit, I’m guessing her interpretation of the Catwoman costume.

Thanks! I thought it looked a little familiar. Kind of ugly though.
