About the radiant shape

The radiant is a rectangular or square cut with trimmed corners and brilliant faceting for intense sparkle. It is one of the most requested shapes for engagement rings and works with solitaire, halo, hidden halo and side stone settings.

Choosing a radiant diamond

Start with carat weight to set the size, then balance color and clarity against your budget. D and E colors look icy white, while F color is the best value in the colorless range. VVS1 and VVS2 are the cleanest grades we stock; VS1 and VS2 are eye-clean and let you choose a larger stone for the same price. Prices for radiant diamonds in our collection range from $287 to $11,197.

Lab grown vs mined diamonds

Lab grown diamonds are real diamonds with the same chemical structure, hardness and sparkle as mined diamonds, graded on the same scales by IGI. They cost a fraction of the price and have a known, conflict-free origin, so you can choose a bigger or better radiant diamond for the same budget.

Setting your radiant diamond

Our jewelers can set your diamond in a solitaire, hidden halo, halo, side stone or three stone engagement ring in white, yellow or rose gold or platinum, or create a fully custom design. Every ring is made to order and approved by you before it ships.
