What is a Radiant Cut Diamond?

Radiant cut diamonds, sometimes referred to as “rectangular brilliant”, are rectangular shaped stones with clipped corners and brilliant cut facets. Designed in 1977 by master diamond cutter Henry Grossbard, radiant diamonds feature 70 facets, more than any other diamond shape. The quantity and style of facets makes radiant cut diamonds extremely brilliant, for a stone that sparkles from almost every angle. 

What is an Emerald Cut Diamond?

Similar to radiant cut diamonds, the emerald cut has a rectangular shape with clipped corners. Emerald cut diamonds feature parallel step-cut facets, creating a mirror-like glow that’s more elegant, understated, and sophisticated compared to the in-your-face sparkle of a brilliant faceting pattern. Emerald cuts were a popular stone during the 1920s Art Deco era, making them perfect for vintage-inspired engagement rings.

The Main Differences Between Radiant and Emerald Cuts

(1) Shape and Facet Structure

Both radiant and emerald cut diamonds are rectangular shapes with clipped corners. Some of them have a squatter rectangular shape, closer to a square, while some are more elongated. However, the real difference between these shapes lies in the faceting styles. 

Radiant cut diamonds feature brilliant facets, which create a highly sparkly stone that sometimes takes on a “crushed ice” appearance. Similar to round brilliant cut diamonds, radiants have triangular and kite-shaped facets, causing the light to bounce dramatically around the shape.

Emerald cut diamonds feature rectangular step-cut facets, causing light to bounce between the facets like a hall of mirrors. This gives emeralds an elegant, subtle shine. Emeralds also have a large, open table (or, the top surface of the stone), which puts the diamond’s clarity on center stage.

(2) Sparkle and Brilliance

“Sparkle and brilliance” is radiant cut’s middle name. 70 brilliant cut facets give these stones a seriously impressive level of sparkle, making them an unmissable center diamond in engagement ring settings. In contrast, emerald cut diamonds flash subtly in the light, creating a stunning reflective effect that highlights the stone’s clarity. These mirror-like diamonds are all about understated elegance—and trust us, you’ll want to stare into yours forever.

(3) Clarity and Inclusions

Clarity is another key difference between emerald and radiant cut diamonds. Emerald cuts have a large table that allows a clear “window” into the stone, making small inclusions more obvious. When purchasing an emerald cut, we recommend prioritizing clarity over the other measures of diamond quality—these include cut, color, and carat. Learn more about the 4 Cs in our Diamond Guide.

Radiant diamonds’ extreme sparkle means they’re much more forgiving when it comes to inclusions. With these diamonds, you can look for a slightly more included stone, in favor of higher color grade or larger carat weight.

(4) Visual Size

Emerald cut diamonds have a larger visual size than radiant cuts because of their large, open table. For example, a 1ct emerald cut diamond will have a larger appearance than a 1ct radiant cut diamond. So if you’re splurging on clarity with your emerald, you can choose a slightly smaller stone, but still have the finger coverage you’re looking for.

(5) Price Differences

Whether you’re shopping for radiant or emerald cuts, a diamond’s price is heavily tied to the 4 Cs. Because emerald diamonds require a higher level of clarity, and also need to be expertly cut in order to make the facets reflect symmetrically, they tend to cost more than radiant diamonds. However, emerald’s larger visual size means that you may be able to compromise on carat weight in order to bring the final price down.

For both cuts, lab-grown diamonds will be more affordable than natural diamonds.

3 Ways to Style Radiant Cut Diamonds

Choosing Between Radiant and Emerald

Emerald and radiant diamonds are both beautiful stones with enduring appeal. Only you can make the final choice, but here’s some factors to keep in mind when making your decision.

(1) Budget: Your total engagement ring budget will determine how much you can spend on the center stone, as well as the complexity of your setting.

(2) Size: Are you looking to max out finger coverage or carat weight within your budget, or would you prefer to prioritize one one of the other 4Cs, such as clarity?

(3) Style: Does your taste lean more vintage, classic, modern, or somewhere else entirely?

(4) Sparkle: Are you looking for dazzling bling, or reserved elegance?

Either way, you can’t go wrong with these gorgeous rectangular diamonds. And at Sarah O. Jewelry, we’re here to guide you through the entire engagement ring buying process, whether you’re shopping for a ready-to-wear ring or want to create your perfect ring with a custom design appointment.
