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.

Choose a 2 carat black oval with a 2 carat white cushion in Mars's Moons (4 carats total), a black emerald cut with a white pear in Neptune's Moons (4 carats), a black marquise with a white cushion in Jupiter's Moons (5 carats), or go bigger with 6 carats total in Mercury's Moons (black emerald cut and white marquise) and Sautern's Moons (black pear and white emerald cut). From $3,570, made to order. More dark and light: black and white diamond rings.
