Wats d brand of necklace Cameron Diaz wore in The Holiday!!?

[Mel Mel]

Cameron wore it in that scene when she was throwing her boyfriend out, perhaps the closest view you can get if you see on the trailer would be when she was typing at her computer and communicating with Kate Winslet.

U can watch the trailer in this url: http://www.sonypictures.com/movies/theholiday/site/main.html
under "Media"

Help me... somebody!!
