Radiant Cut Lab Diamond Engagement Rings

A radiant cut engagement ring has the clean, cropped corners of an emerald cut and the sparkle of a brilliant. It is the shape for people who want a rectangle or square that still flashes like crushed ice. Radiant cut rings are priced from $2,790, each with a lab grown diamond and its IGI or GIA report.

What a radiant looks like in person

The radiant is cut with brilliant facets all the way through, so its light is busy and bright rather than calm like an emerald cut. Under the showroom lights it sparkles hard. By the window in daylight it shows a softer glow. Both are worth seeing, and we will show you both.

The trimmed corners make the shape practical. With no sharp points, a radiant is easier to wear every day than a princess cut, and it fits well next to almost any wedding band.

Square or elongated

Radiants come in two moods. As a rough guide:

• About 1.00 to 1.10: a square radiant, bold and compact.
• About 1.20 to 1.35: a gentle rectangle, the look most people ask for.
• About 1.35 and up: long and slim, it stretches the finger.

Radiants carry a fair amount of depth, so they can look smaller face up than an oval of the same weight. Ask us to show you the millimeter size next to the carat weight. That number tells you more about how big it will look than carats alone.

Settings and pairings

A four prong solitaire keeps the outline sharp. A radiant also looks striking set inside a hidden halo, which adds sparkle from the side. With trapezoid or baguette side stones it becomes a classic three stone ring.

Still deciding on the outline? Look at an emerald cut and a cushion cut on the same visit. The three shapes sit close together, and seeing them on your own hand makes the choice easy.

Color, clarity and the report

Radiants hide inclusions well, so VS2 or a clean SI1 often looks clean to the eye. Color can show slightly at the corners, so many people pick G or H in white gold or platinum. Every stone has an IGI or GIA report; our IGI report guide shows how to read one.
