“Every diamond shape carries a meaning — the magic lies in finding the one that fits your love story.”
Round Cut – The Timeless Classic
If there’s one diamond shape that never loses its charm, it’s the round brilliant cut. People love it for its perfect symmetry and that incredible sparkle you just can’t fake. This shape stands for eternity, loyalty, and lasting love—exactly what you want in an engagement ring.
Round diamonds have 58 facets, each one cut to bounce light around in a way no other shape can match. That’s why so many traditional romantics go for it. It’s classic, but it still feels fresh.
Even in 2025, the round cut leads the way in engagement ring trends. You’ll see it paired with everything from sleek solitaires to those subtle hidden halo settings that give off that effortless, old money vibe. Honestly, this shape just works anywhere—whether you love a clean, modern look or you’re drawn to something vintage.
💡 Blackwell Tip: A round diamond is ideal if you want maximum brilliance and timeless appeal. It’s also incredibly versatile — perfect for those who love elegance that never fades.
“A round cut symbolises forever — refined, radiant, and timelessly true.”
Oval Cut – Modern Elegance
Oval cut diamonds are everywhere right now, and honestly, it makes sense. You get all the sparkle of a round diamond, but with a fresh, stretched-out shape that just looks so chic. There’s an easy elegance to it.
People see the oval as a symbol of grace and individuality. It’s got this timeless beauty, and the elongated shape does something magic—your fingers look slimmer and a bit more delicate. That’s a huge plus if you’re after that low-key, sophisticated vibe.
This style really speaks to modern romantics. It nods to tradition, but there’s a twist—something personal. Soft, but it stands out. Classic, but still feels new. It hits that sweet spot where old meets new. And no matter how you set it—simple solitaire or with a halo—the oval diamond just sparkles from every angle.
💡 Blackwell Tip: For maximum sparkle, choose an oval with a well-balanced length-to-width ratio (around 1.35 to 1.50). It ensures perfect proportions and that signature “flow” people love about this shape.
“The oval cut — modern, graceful, and designed for love that never goes out of style.”
Princess Cut – Bold & Brilliant
If you like your jewellery with a bit of attitude, the princess cut is your diamond. Those crisp corners and that bold, bright sparkle say a lot—it’s modern, sharp, and a little daring. This isn’t a shape that fades into the background. It grabs attention, sort of like the people who choose it.
Back in the 1970s, designers came up with the princess cut for anyone craving something fresher than the classic round diamond. It’s still a favourite, especially for couples who want their rings to shine with personality. The clean lines feel glamorous and timeless, but there’s nothing ordinary about them.
People see the princess cut as a symbol of energy and independence—a fresh start. So when you pick this cut, you’re not just wearing a diamond. You’re making a statement about who you are and what your story looks like.
💡 Blackwell Tip: Because of its sharp corners, the princess cut looks incredible in protective settings like V-prongs or bezel styles. This keeps the stone secure while highlighting its precise, architectural beauty.
“Strong lines, bold sparkle — a diamond made for modern romance.”
Emerald & Cushion Cuts – Vintage Romance
If you’re drawn to that classic, old-school elegance, emerald and cushion-cut diamonds just feel right. Both shapes have a certain depth and character, but each brings its own vibe.
Emerald:
Emerald cuts are all about confidence. You’ve got those long, sleek facets and that big, open table — it’s not showy, but it doesn’t need to be. The emerald cut just glows with this quiet self-assurance. People see it as a symbol of clarity and strength. The lines are sharp, almost architectural, which gives it a look that somehow manages to be both timeless and totally modern.
Cushion:
Cushion cuts, on the other hand, are pure romance. The soft edges, the gentle curves, the way the light kind of glows instead of sparkles — it’s like candlelight. That’s actually what people used to call it, the “candlelight diamond.” There’s something warm and sentimental about it, like it’s meant to be an heirloom, passed down from one generation to the next. It’s a design that just feels full of love and history.
💡 Blackwell Tip: Both of these shapes shine beautifully in vintage-inspired or bespoke settings — perfect for those who want a ring that feels meaningful, personal, and made to last.
“Sophisticated, sentimental, and timeless — vintage romance, reimagined for 2025.”
Pear, Marquise & Unique Shapes – For the Bold & Creative
Tradition isn’t for everyone, and honestly, that’s what makes unique diamond shapes so appealing right now. In 2025, more couples are picking pear, marquise, and even bold, modern geometric cuts to show off who they really are. These shapes don’t scream for attention—they’re just unmistakably personal.
Pear Cut – The Teardrop of Joy
The pear shape is part round, part point, and all about emotion and individuality. People say it stands for tears of joy and fresh starts. There’s something about those gentle curves and that single point that feels romantic and artistic. This one’s for anyone who cares more about meaning than following old rules.
Marquise Cut – The Statement of Passion
With roots in royal history, the marquise cut brings drama and confidence to the table. It’s ambitious, passionate, and impossible to ignore. Its long, elegant shape makes the stone look bigger, so it really makes a statement on your hand.
Modern Cuts – The Rule Breakers
Then you’ve got the modern shapes—kites, hexagons, shields—catching the eye of creative couples everywhere. These cuts are all about freedom and originality. They usually show up in custom designs, where the story and the symbolism matter way more than tradition ever could.
💡 Blackwell Tip: Pair unusual shapes with simple settings — it keeps the focus on the stone’s personality while ensuring it feels timeless, not trendy.
