Buying guide

Ten shapes for a 1 carat center

Every design here comes in all ten shapes. Round gives the most sparkle and suits any style. Oval, pear and marquise are longer stones that make the finger look slimmer and tend to look larger across for the weight. Princess, cushion and radiant cuts are brilliant and squarish or rectangular, while emerald and asscher cuts use long step facets for a calm, glassy look. A heart is the most romantic choice and needs a well-made shape to read clearly at 1 carat.

Styles in the range

Some rings are simple solitaires on a plain or rounded band, and some carry pave lab-grown diamonds down the shank. Others add more: a halo with a three-row pave band, a hidden halo under the center, a cathedral ring with a graduated pave band, a three stone ring, and bands with marquise or pear side accents. The 1 carat figure is the center; accents add to the total.

Picking a karat of yellow gold

Choose 10K, 14K or 18K yellow gold on every ring. A 1 carat lab-grown diamond ring in 14K yellow gold is a popular balance of color and strength; 18K looks deeper and warmer, and 10K is harder and costs less. Finished rings start at about $930, and most are between about $980 and $1,090.
