The dome ring is a format with strong historical jewelry references - it appears in Byzantine and Victorian jewelry as a way to create maximum surface area for stone setting. Rachel Zoe's version centers a green radiant-cut CZ in a white CZ halo within a domed setting in 14K gold over sterling silver - the dome giving the ring three-dimensional presence that a flat setting cannot achieve. The green-and-white CZ combination creates a color contrast that amplifies both stones, and the dome format ensures the center stone is elevated visually as well as physically. A ring with genuine presence on the hand for the wearer who wants color and scale.
