Buying guide

Choosing a shape for a 4 carat center

Every design comes in ten center shapes: round, oval, cushion, princess, emerald, Asscher, radiant, marquise, pear and heart. Round and cushion give the most sparkle. Oval, pear and marquise are elongated, so they cover more of the finger for the same weight. Emerald and Asscher are step cuts with long, clean facets that show off clarity more than sparkle.

Styles to compare

Solitaires keep things simple, with a plain or pave band. Side-accent rings frame the center with smaller lab-grown diamonds, such as pear and round or marquise and round accents. There is a three stone engagement ring, a halo with a three-row pave band, a hidden halo set under the center, a cathedral ring with a graduated pave band, and a vintage-inspired filigree style. Accents are extra weight on top of the 4 carat center.

White gold karat and price

Choose 10K, 14K or 18K white gold. Lower karats contain more alloy, so they are a little harder, while 18K has more gold. White gold is usually rhodium plated for a bright finish, and that plating can be renewed over the years. Prices include the lab-grown diamond center: they start from about $2,400, and most designs start between about $2,700 and $2,800.
