If you're drawn to the romantic charm of vintage jewelry but crave the dazzling sparkle of a modern stone, the cushion cut diamond might be your perfect match. It's a timeless style that beautifully bridges the gap between old-world elegance and contemporary brilliance.
What Exactly Is a Cushion Cut Diamond?
Think of a pillow—soft, inviting, with gently rounded corners. That's the essence of a cushion cut diamond. It features a square or rectangular shape, but without any of the sharp, geometric edges you'd find on a princess or emerald cut.
This classic shape has been around for nearly 200 years. Its ancestor, the "Old Mine Cut," was designed back in the 19th century with one goal in mind: to sparkle magnificently in candlelight. Today’s cushion cuts carry on that legacy, with large facets that create incredible "fire"—those beautiful, colorful flashes of light that make a diamond come alive.
A Quick Look at the Cushion Cut
To get a better feel for this shape, here’s a simple breakdown of its defining features.
Characteristic | Description |
|---|---|
Shape | Square or rectangular with soft, rounded corners. |
Brilliance | Known for exceptional fire, with a sparkle that can look like "crushed ice." |
Style | A perfect blend of vintage, romantic, and classic appeal. |
Durability | Excellent, as the rounded corners are less likely to chip than sharp-edged cuts. |
This unique combination of a soft silhouette and brilliant sparkle makes the cushion cut incredibly versatile. It looks just as stunning in a sleek, modern setting as it does in an ornate, vintage-inspired one.
Of course, the cushion is just one of many options. To see how it stacks up against other popular styles, it's worth exploring the world of different diamond cuts.

The Story Behind the Cushion Diamond
Every cushion diamond is a little piece of history. Its story starts long before modern diamond cutting even existed, back in the 19th century—an era lit by the soft flicker of candles, not the bright glare of electric bulbs.
To really get what a cushion diamond is, you have to picture that time. Diamond cutters developed a cut called the Old Mine Cut, which is the direct ancestor of the cushion we know today. Each facet was meticulously shaped by hand, a labor of love that could take months. The goal wasn't just sparkle; it was to create a deep, romantic fire that would come alive in the warm, gentle light of a ballroom.
This hand-hewn approach gave the stone a squarish shape with large facets, a high crown, and a small table. All of these features were designed to catch and throw back candlelight in big, colorful flashes.
The Standard of Elegance for Centuries
For more than 200 years, the Old Mine Cut—and the cushion cut it became—was the diamond shape. It was the go-to for royalty, aristocrats, and famous jewelers, showing up in some of the most iconic jewelry pieces ever made.
The cushion cut's lasting appeal is all about how it marries softness with brilliance. It doesn't have the sharp, almost severe geometry of modern cuts. Instead, its rounded corners and deep facets create a warm, inviting glow that feels both timeless and intimate.
That vintage heritage is a huge part of its charm. A modern cushion diamond still has hints of that handcrafted past, giving it a character and soul that many newer, more calculated cuts just can't match. It doesn't just reflect light; it almost seems to hold it within the stone.
This rich backstory is a big reason why the cushion cut is so popular again. People aren't just looking for a pretty stone; they want something with a story. They're drawn to that soft, romantic vibe that feels like a nod to a more elegant time. When you choose a cushion, you're not just getting a diamond; you're getting a classic with a compelling story cut right into its facets.
Decoding the Sparkle of Cushion Cut Variations
Not all cushion diamonds are created equal—their unique personality truly comes out in their sparkle. Once you start looking, you’ll quickly notice there are two main "flavors" of cushion cuts, and they each have a totally different vibe.
The first style you'll see is the Cushion Brilliant. This one has a faceting pattern that’s more like a classic round brilliant diamond. The result? Big, bold, and distinct flashes of light. If you love seeing crisp, fiery sparkles dance as the diamond moves, this is the cut for you.
Then there's the Cushion Modified Brilliant. This version has an extra row of facets, which completely changes the light play. Instead of bold flashes, you get a mesmerizing mosaic of tiny, glittering sparkles. Jewelers often call this the "crushed ice" look because it shimmers intensely from every angle.
This infographic gives you a great look at the intricate facet patterns that make each cushion diamond so unique.
As you can see, the size and arrangement of those tiny surfaces are what determine whether you get those big, bold flashes or that glittering, crushed-ice effect.
Cushion Brilliant vs Cushion Modified Brilliant
Deciding between these two styles often comes down to personal preference for a certain type of sparkle. Here’s a quick breakdown to help you see the difference side-by-side.
Feature | Cushion Brilliant | Cushion Modified Brilliant |
|---|---|---|
Visual Effect | Bold, distinct flashes of light ("fire") | A continuous shimmer of tiny sparkles ("crushed ice") |
Facet Pattern | Fewer, larger facets, similar to a round brilliant | An extra row of smaller, more numerous facets |
Best For | Those who love the classic, fiery sparkle | Those who prefer a modern, glittering, all-over shimmer |
Common Nickname | "Chunky Cushion" | "Crushed-Ice Cushion" |
Ultimately, neither cut is "better"—it's all about which kind of sparkle catches your eye.
Shaping the Silhouette
On top of the sparkle, the diamond's overall shape, or silhouette, can also vary quite a bit. This is all determined by its length-to-width ratio.
Classic Square: A ratio between 1.00 and 1.05 gives you that classic, antique-style square cushion. It’s a beautifully balanced and traditional look.
Modern Elongated: Ratios above 1.10 create a more rectangular shape. This is a very popular modern twist that can make the diamond look larger for its carat weight and has a lovely lengthening effect on the finger.
The choice between brilliant, modified, square, or elongated is entirely a matter of personal taste. There is no "better" option—only the one whose unique sparkle and shape speaks to you.
Do you find yourself drawn to the distinct, fiery flashes of the brilliant cut, or are you captivated by the endless shimmer of the crushed ice look?
And while we're talking about diamonds, it's worth noting that this versatile cut isn't just for them. Styles like the Cushion Rectangular Mixed Cut are incredibly popular for other gemstones, too, proving just how timeless this shape really is. Knowing these details is your key to finding a cushion diamond with the exact character you’ve been dreaming of.
So, you're drawn to the soft, romantic glow of a cushion cut diamond. It's a fantastic choice, but like any diamond shape, it comes with its own unique personality—and that means a few things to weigh before making a final decision. Let's break down the good, the great, and the things to watch out for.
One of the biggest draws of a cushion cut is its incredible fire. Those large, chunky facets are practically designed to catch the light and split it into a dazzling rainbow of colors. If you love a vibrant, colorful sparkle, a cushion cut will not disappoint.
Combine that fire with its soft, romantic silhouette, and you get a stone with a timeless character that feels both classic and special.
Built to Last and Offer Great Value
Durability is another huge plus.
Unlike cuts with sharp, pointy corners like a princess or marquise, the rounded, pillow-like edges of a cushion diamond are much less likely to chip. This makes it a fantastic, practical choice for a ring you plan on wearing every day.
But here’s where the cushion cut really shines: its value. The cutting process is more efficient, meaning less of the original rough diamond is wasted. This often translates to a more affordable price per carat compared to the ever-popular round brilliant.
Plus, the shape can make the diamond appear larger than its actual carat weight. You get more visual impact for your budget, which is always a win. For a deeper dive, you can see how cushion diamond pricing compares to other cuts on stonealgo.com.
A Few Things to Keep in Mind
Now for the trade-offs. The very same large, open facets that create all that beautiful fire can also act like a window, making inclusions (tiny internal flaws) easier to spot. To get a stone that looks clean to the naked eye, you'll likely want to aim for a clarity grade of VS2 or higher.
Color is another key consideration. Cushion cuts tend to hold onto color more than other shapes. This means a diamond with a lower color grade, like a J or K, might have a noticeable warmth or a faint yellow tint. If you're looking for that bright, icy-white look, it’s usually best to stick with a color grade of H or higher.
Knowing these nuances helps you pick the perfect cushion cut that balances beauty, durability, and your budget.
How to Select the Perfect Cushion Diamond
Picking out a cushion diamond isn't about ticking boxes on a spec sheet; it's about getting to know the unique character of each stone. Think of this as your playbook for finding a truly spectacular diamond, moving beyond the basic 4 Cs to focus on what makes a cushion cut shine.
Here's something you might not know: unlike round brilliant diamonds, the Gemological Institute of America (GIA) doesn't give cushion diamonds a "Cut" grade. This puts a little more power—and responsibility—in your hands. But don't worry, figuring out what makes a great cushion cut is easier than it sounds.
Look Beyond the Standard Cut Grade
Since there's no official cut grade from the GIA, you'll have to be the judge. Your eyes are your best tool here. To do this, you’ll want to look at two crucial indicators of a well-cut cushion: symmetry and polish.
Thankfully, the GIA does grade these two factors. You should look for stones with Excellent or Very Good grades in both categories.
Symmetry is all about how precisely the facets are arranged. If the symmetry is off, the diamond can look unbalanced and won't return light as well as it should.
Polish refers to the smoothness of the diamond's outer surfaces. A high-quality polish means the facets are like perfect mirrors, free of any blemishes from the cutting process that might dull the sparkle.
These two grades are your best stand-in for an overall cut grade. Getting them right is key to ensuring your diamond has that brilliant, fiery performance you're looking for.
Finding the Sweet Spot for Color and Clarity
The large, open facets of a cushion cut are part of its charm, but they also act like windows into the stone. This means they can show off hints of color or tiny internal features (called inclusions) more easily than other cuts. That’s why getting the Color and Clarity grades right is so important for maximizing your budget.
For color, a grade of G or H is often the perfect balance. To the naked eye, these diamonds look beautifully white, especially once they're set in a ring. The best part? They come at a much friendlier price point than the top-tier D, E, or F color grades.
When it comes to clarity, your goal is to find a diamond that is "eye-clean." This doesn't mean it has to be flawless—it just means you can't see any inclusions without magnification.
You'll often find the best value in the VS2 (Very Slightly Included 2) or SI1 (Slightly Included 1) clarity ranges. A well-chosen SI1 can look completely clean to the naked eye and save you a significant amount of money.
This kind of smart, strategic approach is what separates a good buy from a great one. To really sharpen your eye, it helps to dig deeper into understanding diamond grades. While natural diamond prices can fluctuate, market analysis reveals that cushion diamonds have consistently held their value, proving their timeless appeal. By focusing on these key details, you can choose a stunning cushion diamond with confidence.
Common Questions About Cushion Diamonds
As you get closer to choosing a cushion diamond, a few practical questions are bound to pop up. It's totally normal. Let's walk through some of the most common ones so you can feel completely confident in your decision.
Does a Cushion Cut Diamond Look Smaller for Its Carat Weight?
This is a great question, and the answer isn't a simple yes or no. A cushion cut tends to be a "deep" stone, meaning it holds more of its carat weight in its pavilion (the bottom part of the diamond). Because of this, it can sometimes have a slightly smaller face-up measurement than a round brilliant of the exact same weight.
But here's the trade-off: that depth, combined with its large facets, creates an incredible sense of dimension that pulls you right into the stone. If you're looking to maximize how big it looks on the hand, an elongated cushion cut is a brilliant way to go. It gives you a larger visual footprint without needing a higher carat weight.
Are Cushion Diamonds Cheaper Than Round Diamonds?
Yes, they almost always are. When you compare them carat-for-carat, a cushion cut diamond will typically cost 25-35% less than a round brilliant diamond of similar quality.
It all comes down to how the diamond is cut from the original rough stone. The cushion shape is much more efficient, allowing the cutter to preserve more of the raw diamond and waste less. That efficiency gets passed on to you, often letting you secure a larger or higher-quality cushion for your budget.
What Is the Best Ring Setting for a Cushion Diamond?
One of the best things about the cushion cut is just how versatile it is. It truly looks incredible in almost any setting, but a few styles have become favorites for very good reasons.
Halo Setting: This is a go-to for a reason. A halo beautifully traces the diamond's soft, pillow-like shape, adding a ton of extra sparkle and making the center stone look even bigger.
Solitaire Setting: If you're after a clean, timeless look, a simple solitaire is perfect. It puts all the focus on the diamond's unique silhouette and classic fire, with no distractions.
Vintage-Inspired Setting: A cushion cut has a rich history, and a vintage-style setting with detailed metalwork, filigree, or delicate pavé accents is a beautiful way to honor that romantic, old-world vibe.
Ultimately, the "best" setting is the one that speaks to your personal style. Whether you love sleek and modern or ornate and antique, the cushion cut can do it all.
Looking at different ring styles, like the ones in our guide to lab-created diamond rings, is a great way to get inspired and find the perfect home for your stone.
Why Does My Cushion Diamond Look Different From Another?
That's the magic of the cushion cut! Unlike a round brilliant, which is cut to a very strict, standardized formula, cushions are all about individuality. There's no single blueprint.
Every cushion has its own unique personality, defined by its facet pattern (like brilliant or modified), how rounded its corners are, and its length-to-width ratio. This is exactly why you'll want to see a cushion diamond up close—either in person or through high-quality video—before you buy. You're not just buying a stone; you're choosing a one-of-a-kind piece.
