There’s something quietly poetic about a piece of jewellery that catches the light just right — that tiny, sparkling moment that makes you pause. For me, that moment came the first time I saw a cushion diamond under natural sunlight. It wasn’t the biggest stone I’d ever seen, or the most flamboyant. But it had character — a kind of soft, romantic glow that felt timeless.
If you’ve ever been curious about what makes a cushion diamond so special, you’re not alone. These stones have been captivating jewellers and romantics alike for centuries, yet they’re enjoying something of a renaissance right now — thanks, in part, to changing tastes and the rise of man made diamonds that make fine jewellery more ethical and accessible than ever.
Let’s unpack why this vintage-inspired gem has become the quiet darling of the modern engagement ring scene.
A Little History Behind the Cushion Diamond
Before the razor-sharp sparkle of round brilliants took over the market, cushion-cut diamonds were the choice for engagement rings. They date back to the 18th century, originally known as the “mine cut” — a hand-shaped design inspired by the diamonds coming out of Brazilian and Indian mines.
The cut evolved over the years, becoming more refined, more symmetrical, and more efficient at reflecting light. But it never lost its defining feature: that softly rounded square shape with pillow-like corners. (And yes, that’s where the “cushion” name comes from.)
Honestly, there’s something nostalgic about them. They remind me of a time when jewellery was less about perfection and more about personality. Cushion diamonds often have broader facets that reflect light in flashes rather than sparkles — it’s less glittery, more glowing. Think candlelight rather than camera flash.
For many people, that warmth and subtlety are exactly what makes them so irresistible.
The Modern Appeal: Why Cushion Diamonds Are Back
You might not know this, but the cushion cut has quietly become one of the most popular diamond shapes for engagement rings again. It’s not hard to see why.
The shape has a vintage charm that stands out in a sea of uniform round brilliants. But it also has enough versatility to suit almost any style — modern, bohemian, minimalist, or traditional. Whether set in yellow gold, rose gold, or sleek platinum, cushion diamonds adapt beautifully.
Designers love them because they play well with different settings. A halo of smaller diamonds can amplify their glow. A solitaire setting lets their shape take centre stage. Even a bezel design can give them a clean, contemporary edge.
And then there’s the emotional factor. Cushion diamonds just feel more romantic. They’re the kind of stone that looks like it belongs in an old love letter or a family heirloom — even if it was made yesterday.
If you’ve ever browsed through a collection of engagement rings and found yourself drawn to one without knowing why, there’s a good chance it had a cushion cut.
Understanding the Cut: What Makes Cushion Diamonds Unique
Now, let’s talk craftsmanship — because the cushion cut isn’t as straightforward as it looks.
A cushion diamond usually has 58 facets, but cutters often tweak proportions to balance fire (the flashes of colour you see when it catches light) and brilliance (the white sparkle). Some have a “crushed ice” look — almost glitter-like — while others have larger, chunkier facets that give off more distinct flashes of light.
It’s a bit like comparing different photography lenses: one creates dreamy, soft bokeh; the other delivers crisp, defined highlights. Neither is better — it just depends on your taste.
The ratio also matters. A 1:1 ratio gives you a perfect square, while a 1:1.2 ratio elongates the shape slightly, making it look more rectangular. Many jewellers will tell you that elongated cushions can even make your fingers appear slimmer — though that’s entirely subjective, of course.
Still, it’s worth spending time comparing a few before deciding. No two cushion diamonds look exactly alike, and that’s part of their magic.
The Ethical Sparkle: Rise of Man Made Diamonds
Now, here’s where the conversation gets interesting. Because today, the most beautiful cushion diamonds don’t necessarily come from deep within the earth.
With the rise of man made diamonds — also known as lab-grown or lab-created diamonds — buyers have more choice than ever before. And not just in terms of price.
Man made diamonds are grown in advanced laboratories that replicate the same conditions found underground. The result? A diamond that’s chemically, physically, and optically identical to a mined one. The only difference is where it was born.
I’ve spoken with a few jewellers in Melbourne who specialise in these stones, and they all say the same thing: customers love that they can choose something sustainable without compromising on quality or beauty. Many even find that lab-grown diamonds are brighter and clearer, since they’re produced under controlled conditions.
For couples who care about ethics and environmental impact, this is huge. The idea that your engagement ring can symbolise not only love but also mindful living — that’s something special.
The Price Question (and Why Cushion Diamonds Are a Smart Choice)
Let’s be real — buying a diamond can feel daunting, especially when prices fluctuate wildly based on shape, clarity, and carat weight.
One of the best-kept secrets in the jewellery world is that cushion cuts often cost less per carat than round brilliants of similar quality. Why? They waste less material during cutting and aren’t as in-demand (though that’s changing fast).
That means you can often get a larger stone for the same budget — and because cushion cuts have slightly deeper proportions, they tend to look “plumper” on the finger, too.
Combine that with a lab-grown origin, and the savings can be significant. I’ve seen couples upgrade from a 1.0 carat mined diamond to a 2.0 carat man made cushion diamond without stretching their budget. It’s not just about size, either — they’re getting cleaner stones, ethically sourced, and crafted with the latest technology.
Honestly, it’s one of those rare win-win situations in fashion and design.
Setting the Scene: Styles That Elevate a Cushion Diamond
If you’re exploring settings, this is where creativity really shines.
Halo setting: Surrounding your cushion diamond with a halo of smaller diamonds creates an illusion of greater size and sparkle. It’s elegant without being ostentatious.
Solitaire: Minimalist, timeless, and always classy. The cushion cut’s curves soften the look, making it feel romantic rather than stark.
Vintage-inspired: Think milgrain detailing, filigree patterns, or art-deco motifs. These pair beautifully with the antique energy of the cushion shape.
Three-stone rings: Flanked by smaller diamonds or coloured gemstones, the centre cushion cut becomes the undeniable hero of the piece.
A well-chosen setting doesn’t just protect your stone — it tells a story. And that’s the beauty of cushion diamonds: they adapt, evolve, and somehow always feel personal.
A Note on Colour and Clarity
Cushion cuts are a bit more forgiving when it comes to clarity than, say, emerald or Asscher cuts, which have open facets that reveal inclusions easily. Still, it’s worth looking for stones graded VS2 or above to keep things crisp.
Colour, on the other hand, can be a fun playground. Because of their slightly warmer light return, cushion diamonds often look stunning in near-colourless grades (like G–H). Some even prefer faintly tinted stones — especially when set in yellow or rose gold — because the warmth complements the metal.
It’s all about harmony rather than chasing the highest grades on paper. Jewellery is emotional; it’s not a spreadsheet.

What I love most about this new wave of jewellers is their transparency. They’re not trying to romanticise mining or inflate mystery; they’re celebrating artistry, precision, and conscious choice. And that feels like a healthier kind of luxury.
Why the Cushion Diamond Speaks to This Moment
Maybe it’s just me, but the cushion diamond feels very now — even though it’s centuries old. In an age where trends change faster than we can scroll, it’s comforting to see something enduring, something with substance.
People today are craving meaning. Whether it’s in slow fashion, sustainable design, or mindful consumption, we’re collectively moving toward stories that last. A cushion diamond — especially one that’s ethically created — perfectly captures that mindset.
It’s romantic without being flashy. Thoughtful without being preachy. And it carries a quiet elegance that doesn’t need to shout for attention.
Final Thoughts: More Than Just a Sparkle
At the end of the day, jewellery isn’t really about carats or certifications. It’s about what it represents — connection, memory, a moment frozen in time.
The cushion diamond embodies that perfectly. It bridges the past and the future, offering that soft candlelit glow of vintage romance with the clean conscience of modern innovation. Whether you’re drawn to its pillowy silhouette, its history, or the ethics behind how it’s made, it’s hard not to fall in love with it just a little.
