If you are wanting a website that not only showcases jewelry but will transport you to another world, Van Cleef & Arpels website will do just that!  Make sure you have your volume turned on, because the soothing music will have you in a relaxed trance.  The Jewellery Collection tab has a drop-down list of clickable collections, each are fun to explore.  Their jewelry has been worn by celebrities, featured in movies, and has walked down red carpets.  I like the trinket boxes that are bejeweled in diamonds and sapphires.  Luxury overload!
