Toi et Moi Black Diamond Engagement Rings
A toi et moi ring ("you and me" in French) sets two stones side by side on one band, one for each of you. In our Celestial collection, each ring pairs a natural black diamond with a white lab-grown diamond of a different shape: dark and light, two people, neither one hiding the other. The black diamond is natural and color enhanced; the white one is lab-grown, as each listing states.
