Go big. It is still a real diamond.

Every design here is built around a center of three carats or more, some as big as four and a half, so the setting is proportioned for a statement stone from the start. Lab-grown is how a diamond this size stops being a fantasy.

Pick your shape: a three-carat oval, emerald, marquise, pear or radiant, in white or in pink and blue. All rings: lab-grown diamond rings.
