Buying guide
Every ring offers ten shapes: round, oval, cushion, princess, emerald, Asscher, radiant, pear, marquise and heart. At 7 carats the shape changes how large the stone looks on the hand. Elongated shapes such as oval, pear and marquise spread their weight over more length and tend to look bigger from above. Emerald and Asscher cuts show long, step-cut facets and a clear, glassy look. Round and cushion stones give the most sparkle and suit a classic solitaire.
A plain band keeps the 7 carat lab-grown diamond center as the only stone, and a thin band makes it look even larger. A pavé band adds small lab-grown diamond accents along the shank for extra sparkle, and the accents add to the ring's overall carat weight. Some rings also have a hidden halo, a ring of small stones under the center that shows from the side, or a cathedral setting, where the band rises in arches to hold the center higher. Most bands are about 1.8–2.2 mm wide, which keeps the focus on the center.
Gold comes in 10K, 14K or 18K, in white, yellow or rose. Higher karats hold more pure gold and a richer color; 14K is a common balance of color and hardness. Platinum is naturally white, dense and hard-wearing, and it costs more than gold. White metals make a colorless center look icy, while yellow and rose gold add warmth around it.

Here, a 7 carat solitaire ring with its lab-grown diamond center starts at about $5,900, and most cost between about $6,200 and $6,400 in the lowest-priced metal. The price includes the center stone and the setting. Platinum and 18K gold cost more than 10K or 14K gold. Lab-grown diamonds cost far less than natural diamonds of the same size, which is why a stone this large stays within reach.
