Juicy Couture site http://www.juicycouture.com/ Shops: try small but expensive jewelry shops or if you WAN stores tlarger: John Lewis (London only they are good) Selfridges & Co Some stores Harvey Nichols
Hey, I definitely recommend Twenga, they have absolutely loads of jewelry on their site so I would say that you can find something. Otherwise, I'd give the site Juicy Couture Party! :)
