does anyone here know if you can get a stone other than a diamond set in "designer settings" such as the vatch x-prong or the ritani endless love? My dream engagement ring would have to be a pink sapphire set in a ritani endless love setting with the halo. if i wanted to do this would i have to have a setting custom made or can i buy the setting from ritani and get my sapphire set in it after, or even by ritani?
