Radiant Cut Engagement Rings

The Radiant Cut

Radiant Cut Engagement Rings

A radiant cut diamond is a rectangle or square with the corners cut off and a brilliant facet pattern inside it. It keeps the architecture of an emerald cut and replaces the long step facets with 70 small ones, so the diamond reads as sharp lines from across the room and as fire up close. It is the shape for someone who wants the geometry of an emerald cut and the light of a round, and who does not want to choose.

Every ring in this collection is made to order in our Los Angeles atelier, modeled around the exact measurements of the radiant diamond you select. The cut corners are held by the prongs, which is where a radiant is strongest, and the gallery is shaped to the diamond's ratio rather than to a template.

Two ways to own one

Build your ring. Choose a radiant setting below, then pair it with a natural or lab radiant diamond from our inventory. A ROSI™ Score Report, our gemological intelligence, reads the cut performance and fair market position of any natural diamond you are considering, and John Anderson, our Lead Gemologist, reviews the shortlist with you.

Choose a Select ring. The Select rings in this collection arrive complete, with an IGI certified lab radiant already matched to the setting in the carat weight you choose.

How to choose a radiant diamond

• Ratio. 1.00 to 1.05 reads as a square radiant. 1.20 to 1.35 reads as a rectangle and elongates the finger. Both are correct; the setting is modeled to whichever you choose.
• Color. The brilliant faceting hides body color better than a step cut. H faces up white in platinum and white gold; yellow and rose gold are forgiving down to J. A radiant is also the cut that shows a fancy yellow diamond at its best.
• Clarity. The same faceting hides small inclusions. VS2 is usually clean to the eye; SI1 often is, and the ROSI™ report tells you when it is not.
• Corners. Look for even cut corners on all four sides. Uneven corners are the first thing a trained eye sees on a radiant and the last thing a certificate mentions.
• Setting. Four prongs on the corners for a clean solitaire. A halo adds spread. Trapezoid or tapered baguette side diamonds make a three stone ring that stays in the same geometric language.

Talk to a jeweler before you decide

Ratio, corner symmetry and depth decide how a radiant performs, and none of the three is obvious from a listing. John Anderson, our Lead Gemologist, compares the candidates with you on the phone or by video. Call 1-800-779-1726 or request a consultation. There is no charge and no obligation.
