I dreamt about a Yellow Necklace

and since then I've been on the hunt to find one as pretty as the one I remember in my dreams.  Random I know, right?  But the more I think about it, the more I love the idea of a pop of yellow against a navy blazer, black tee, and the list goes on and on.  Which necklace is your favorite?
