Sapphire And Diamond Engagement Band, Opposites Attract, 18k Yellow GoldI love how two opposites come together to compliment each other perfectly. The white and bright diamonds and rich blue sapphires set in a custom 18k yellow gold setting. The gems are set a jour with an open back. I love this ring as an engagement band or statement wedding band.
