9K Yellow Gold | 2ct. eq. Centre Stone One of our fabulous Princess CARAT* stones in a four prong setting. As a standard we finish off all our jewellery in a manner befitting its quality, the same way the finest jewellers in the world do. We complement the gold nearest the stone with various colour tones. This is done to give the featured stone a colour boost and to almost hide the prongs with the colour of the stone.
