She's worn it in another episode, but I'm not sure which one. Possibly around the time she was with Aidan (2nd time). It seems to have 2 gold chains attached to it with 2 diamonds/rhinestones-1 on either strand.
I appreciate any info anyone may be able to give me! I love it and either would buy it or even try to make it myself, but I can't find a photo of it. I've searched every which way possible!! Thanks in advance for any help!
P.S. She is wearing another necklace with it that she wore in the episode with David Duchovny!
