14K Gold Radiant Lab-Grown Diamond Ring vs 14K Gold Marquise Lab-Grown Diamond Ring

Buy the radiant ring if you want the bigger, more brilliant center stone and a sturdier shape on the hand. Buy the marquise ring if you want a long, elegant look and a wider size range. Both are 14K gold with F-color lab-grown stones and prong settings, and both weigh about the same. The radiant's clipped corners resist knocks better than the marquise's two thin points, which owners of marquise cuts often say snag on clothing and need more careful wear.

• Choose the radiant ring if you want a 2-carat center stone, a brilliant-style cut with more sparkle, and corners that hold up to daily knocks.
• Choose the marquise ring if you prefer a long, slender shape and need a size outside 5 to 9, since it runs from 4 to 10.
