Two Rectangles, Two Kinds of Light
Emerald and radiant cuts share a rectangular outline with cut corners, but they handle light in completely different ways. Here is how they compare in sparkle, clarity, size and price, with real measurements and prices from our diamond search.

An emerald cut is a step cut: long, parallel facets arranged like steps, which give broad flashes of light and a calm, glassy look often called a hall of mirrors. A radiant uses the same rectangle with cut corners but fills it with brilliant facets, the kind used on a round, so it sparkles brightly. Both have cropped corners, which protect the stone and suit everyday wear.
| Feature | Emerald | Radiant |
|---|---|---|
| Facets | Step cut: long, parallel facets | Brilliant cut: many small facets |
| Light | Broad flashes, a calm, glassy look | Lively sparkle, close to a round |
| 1 carat size face-up (our search) | About 6.9 by 4.8 mm | About 7.1 by 5.0 mm |
| Clarity | Shows inclusions more; choose VS2 or better | Hides small inclusions well |
| Typical 1 carat price, lab-grown (our search) | About $430 | About $440 |
| Typical 2 carat price, lab-grown (our search) | About $990 | About $950 |
An emerald cut looks understated and architectural, with a vintage, Art Deco feel; its beauty is in clean lines and clarity rather than sparkle. A radiant looks brighter and more contemporary, with the fire of a brilliant cut in a structured shape. If you love a sleek, quiet look, choose the emerald; if you want the most sparkle from a rectangle, choose the radiant.
An emerald cut's open facets let you see deep into the stone, so inclusions and any tint of color are easier to notice. Many buyers choose VS2 clarity or better and G color or better, and check the photos to confirm the diamond looks clean. A radiant's many small facets break up the light and mask small inclusions, so an eye-clean radiant is often easier to find at the same grade.
Our guide Beyond the Grade explains how inclusions show in each cut.
In our lab-grown diamond search, a typical 1 carat emerald cut measures about 6.9 by 4.8 mm and a typical 1 carat radiant about 7.1 by 5.0 mm, so the radiant faces up a little larger. Both typically have a length-to-width ratio of about 1.4 to 1.5, the classic rectangle; a radiant can also be nearly square. Either shape can be set east-west, turned across the finger, as in our Elowen rings.
