This melange of happy colours just makes me smile. Italian designer Marco Bicego uses reverse set topaz, amethyst, lemon citrine, garnet and citrine in a bezeled 18k setting for a ring that is just a fun piece to wear. Part of his Jaipur collection, it really is a pretty interpretation of the vibrancy of traditional Indian jewellery and colours. Retailing for USD $1455 at Neiman Marcus.
