Ok well I have just got back from the Jewellery Quater and I found the ring and got it today!! ended up getting quite a good deal I think, its a Princess Cut, 0.35carat diamond, tiffany style setting, platinum, they had it marked at £1350.00 and I managed to get them to knock 40% off and got it for £810!! they valued it at £1500 which they have provided certification for and also GIA certified, so all in all I am quite happy!!
Just hope she likes it now!!!!
