Both popular styles, the radiant cut and cushion cut, often attract cross-shopping due to their similarities. In fact, at first glance, it can be hard for the untrained eye to tell them apart. Luckily, that’s what we’re here for. While quite similar, there are a few key differences to note before selecting which of these cuts is for you.
Age
While it likely doesn’t matter to you when the cut was created, it is one of the differences between the two. The radiant cut is a much more modern style created in the late 1970s. Cushion cut engagement rings, on the other hand, are a much older and more classic style, dating back to sometime during the 18th century. If the modern versus classic style debate is important to you, there’s definitely a difference between the two cuts.
Angles
As the name suggests, the cushion cut is, well, a little cushier. While you may not notice it at first glance, the angles on the cushion cut are softer than those of the radiant cut. The more modern radiant cut has sharper and more defined 45-degree angles, while cushion cut engagement rings are a bit more rounded with gently curved sides. This is likely one of the two biggest things to consider when choosing between the two cuts.
Look a little closer, though, and you'll notice the corners tell the whole story. A cushion cut diamond features softly rounded corners. Think of them as gently curved edges that give the stone its pillow-like silhouette. A radiant cut diamond, on the other hand, has beveled corners (also called trimmed or cropped corners). Those small clipped angles at each point give it a more structured, geometric outline. It's a subtle difference, but it's one of the clearest ways to tell the two apart side by side.

Size
This is the other big factor when shoppers are choosing between cushion and radiant cuts. Cushion cuts tend to have a pretty square shape. There are some cushion cuts that are slightly rectangular, though you wouldn’t notice if you weren’t looking for it. Overall, cushion cuts are squarer.
Radiant cut engagement rings usually have a more rectangular shape than their cushion cut counterparts. They also tend to be much more obviously rectangular, unlike slightly rectangular cushion cuts. However, they too have some variety in size and length-to-width ratio. As a good rule of thumb, regardless, cushion cuts are more square, and radiant cuts are more rectangular.
This gets even more interesting when you go elongated. An elongated radiant is noticeably long and lean. It stretches across the finger in a way that can make the center stone look larger than its carat weight suggests. That visual stretch is sometimes called a larger face-up appearance, and it's a big reason shoppers love elongated stones. An elongated cushion cut, by contrast, is also longer than a standard square cushion, but its rounded corners keep things softer and more romantic-looking on the finger. Both are gorgeous options. The elongated radiant just reads a little more bold and modern, while the elongated cushion leans more vintage and feminine.
Shine
Both cuts reflect light and color well, though not equally. As the name suggests, the radiant cut tends to have a better shine and more intense sparkle and has an easier time picking up the light than the squarer cushion cut. Now, is it going to be an earth-shattering difference? Well, no. If you’re splitting hairs trying to make a decision, the radiant cut has a bit more luster, and a cushion cut reflects a bit more color in rainbow colored flashes.

Radiant vs. Cushion Diamond: Facets and Sparkle
Here's where things get a little fun. The way a stone handles light comes down to its internal facet pattern, or faceting style, basically the arrangement of tiny flat surfaces inside the stone that reflect and bend light.
A radiant cut diamond, a modified brilliant, is known for its highly active, lively sparkle. It typically features around 70 facets, which gives it a lot of surface area to play with light and hides inclusions well. The result? A bright, flashy sparkle that catches attention from across the room.
A cushion-cut diamond, also a modified brilliant, generally has around 58 facets, though this can vary depending on the specific cut style. Its facet pattern tends to produce a softer, chunkier light return from larger facets, sometimes described as a "crushed ice" effect or a deeper, glowing fire. That fire is that warm, rainbow-like burst of color you see when light hits the stone at just the right angle. Cushion cuts are especially known for it.
So what does this mean for you? If you love a stone that sparkles bright and snappy, the radiant cut is your go-to. If you prefer a warmer, more romantic sparkle with lots of fire, the cushion cut delivers it beautifully.
Which Engagement Ring Setting Works Best?
The good news is that both cuts are incredibly versatile when it comes to settings. But some pairings do work especially well.
A solitaire engagement ring setting is a great choice for either cut. It puts all the focus on the center stone and lets the diamond shape do the talking. For a radiant cut, a sleek and minimal solitaire looks sharp and modern. For a cushion cut, it creates a clean, classic look that never goes out of style.
Want something with a little more drama? A halo setting surrounds the center stone with a ring of smaller accent stones, which can make the center stone appear even larger. A halo works beautifully on both cuts. It adds detail and brilliance to a radiant cut and enhances the soft, romantic feel of a cushion cut.
Ultimately, your personal style matters more than any "rule." A radiant cut tends to complement sleek, geometric settings, while a cushion cut pairs naturally with softer, more ornate designs. But honestly? If you love a setting, go for it.
Radiant Cut vs. Cushion Cut: Which Should You Choose?
Still on the fence? Here's a quick breakdown:
- Choose a radiant cut if you love sharper lines, straight edges, beveled corners, and a more geometric, modern diamond shape
- Choose a cushion cut if you prefer rounded corners and a softer, more romantic look
- Consider an elongated radiant or elongated cushion if you want a longer silhouette on the finger or an east-west setting
- Think about your overall ring design and engagement ring setting, not just the center stone shape
- Compare both side by side, in person or through product photos, and go with whichever one feels most like you
That’s really all there is to it. It’s common for shoppers who like one style to appreciate the style of the other and cross-shop them. The bottom line is that they’re both timeless styles that’ll hold on and look good through everyday wear for years to come because of their simplicity and brilliance.

Frequently Asked Questions
Is a radiant cut or cushion cut more expensive?
Prices are usually close. Both typically cost less than a round brilliant diamond of the same carat weight, with final price depending on color, clarity, and cut quality.
Which sparkles more, a radiant cut or cushion cut?
Radiant cut diamonds usually deliver brighter, more intense sparkle, while cushion cut diamonds show a softer glow with more colorful fire.
Does a radiant cut look bigger than a cushion cut?
Often, yes. An elongated radiant spreads across the finger for a larger face-up appearance, while a square cushion carries more of its weight in depth.
Which cut hides inclusions better?
Both hide inclusions well thanks to their brilliant-style faceting, which is why many shoppers can choose a slightly lower clarity grade without seeing a difference.
Are radiant and cushion cut diamonds good for everyday wear?
Yes. A cushion cut’s rounded corners and a radiant cut’s trimmed corners both protect the stone from chipping, so either shape suits everyday wear.
