This collar is an essential in any jewellery wardrobe.  It looks stunning when worn by itself, but can change it's look at any moment simply by adding a different pendant.  It gives a totally different look to your jewellery than a simple chain.  This is a U shaped collar that is 3mm wide.  The collar will fit most necks as it spreads to slide around the neck.  The tension of the piece keeps it sitting firmly an your neckline.
