I've been told them use different diamonds depending on the color metal that will go around them. My mother gave me her old wedding set which I knew I'd never wear in that fashion and after 15 years I decided to have it turned into a bracelet. As your setting was in white gold and I'm a fan of yellow gold I had them put a bexel in white gold around each diamond then connect each to a yellow gold piece between. I wear that bracelet quite often now. Some of my antique jewerly I find has the white gold around the diamonds and then they added the band in yellow gold. As someone mentioned the rules these days are to wear whatever you like, not worrying about which color metal they're set in..............so I do.
