I saw this necklace and literally screamed "ARGHHHHHHHHHHHH! I LOVE IT!
It is gorgeous! I not only love the colour I love the design of it.
It is a Kenneth Jay Lane 22-carat gold-plated sodalite necklace.
It would be perfect teamed with a white t-shirt, or over a black dress.
It is £60 from Net-A-Porter.
