Whats your opinions on diamonds vs white sapphires? I have a diamond engagement ring set that I really want to use for my engagement ring (at the moment they only fit my pinky, size mistake) but I also have an antique white sapphire (tiny diamonds on the band) I got from my mother who gave to me to use as my engagement ring set(the marquis shaped one) I would like to know your opinions on it? Whats your favorite?
