If the polished silvery finish is your favourite one, then you need to have a few white gold pendants. They are great gifts as well so they can save you when you have no idea what to get to a nice birthday lady.
Match the pendants with one of the fine necklaces and you'll get a magnificent accessory that will capture attention and add sparkle even to a regular casual outfit. These charms can be simply heart-shaped, oval, cross-shaped or feature tiny patterns that decorate them nicely. Also, you can go for fancy lockets that look as if they just got out of a fairy tale.
