After all my excitement I just ended up with this gorgeous 6x4 diamante photo frame (or what Zara call metal rhinestone frame) as I had already spent quite a bit by that point!
It was only £19.99 and is really sparkly. My only issue with it is the size is a bit misleading.... It say's it's a 6x4 inch frame but actually its bigger than that as when I placed a 6x4 photo in it there were gaps around the side. So what you really need to do is use a 7x5 photo and trim it down.
