I don't think it's possible to tell, unless we had pictures taken from the same angle. I found one site that said prongs were added after Diana received the ring. The prongs would have been repaired after something damaged some of them when Kate wore the ring in Australia. The number or size or angles of the prongs might have been changed again. Assuming she was wearing the real ring. In all the pictures I found, the band of the ring is much darker gold than either lady's Welsh gold engagement ring.
Interesting to note that Diana had a diamond eternity band, which she wore on her right hand. I wonder whether Kate wears the same one, or whether William bought her a new eternity ring.
