Cushion Cut Engagement Rings UK 2026 | Bespoke

The first time I truly fell in love with a cushion cut diamond, I was sitting at my bench at one of Britain's largest fine jewellery manufacturers, turning a stone under a loupe. It was an old mine cut, slightly irregular, with a warmth that no modern brilliant could replicate. The soft, rounded corners caught the light in a way that felt almost organic, like a river stone polished by centuries of water. I remember thinking: this is the shape that tells a story.

That moment has stayed with me through my years at the School of Jewellery in Birmingham, through three Goldsmiths' Craft and Design Council awards, and into every bespoke cushion cut engagement ring I design today at Silux London. If you are considering a cushion cut engagement ring in the UK, whether bespoke or from an existing collection, this guide is for you.

Why Cushion Cuts Are Having Their Moment in 2026

Cushion cuts have always had a loyal following, but 2026 has brought them firmly into the spotlight. The shift away from uniformity in fine jewellery is accelerating. Couples are choosing stones with character over clinical perfection, and the cushion cut delivers exactly that: a shape with heritage, softness, and a distinctive play of light that feels both timeless and current.

There is also what the industry has quietly called the "Taylor Swift effect." High-profile elongated cushion cut engagement rings have introduced the shape to a generation that might otherwise have defaulted to a round brilliant. But beyond celebrity influence, the real driver is something deeper. People are searching for meaning. They want a ring that reflects who they are, not simply what is popular. The cushion cut, with its roots stretching back over two centuries, carries a sense of history that resonates with couples who value substance over trend.

Search interest for "cushion cut engagement ring UK bespoke" and "elongated cushion cut ring UK" has risen steadily throughout 2025 and into 2026. What I find particularly interesting is that this demand is not just for ready-made rings. It is overwhelmingly for bespoke pieces, rings designed from scratch around a specific stone, a specific hand, a specific love story.

Old Mine vs Modern Cushion vs Elongated: What's the Difference?

If you have started researching cushion cut diamonds, you will quickly discover that the term covers a family of shapes rather than a single cut. Understanding the differences will help you choose the stone that truly speaks to you.

The old mine cut is the original. Cut by hand before the age of machine precision, old mine cut diamonds have a high crown, a small table, and broad, chunky facets that produce a warm, candlelit sparkle rather than the sharp brilliance of modern stones. Each one is unique, shaped by the hand of the cutter who fashioned it, often over a century ago. The old mine cut engagement ring is experiencing a significant revival in 2026, driven by collectors and romantics who prize individuality above all else.

The modern cushion brilliant takes the classic cushion silhouette and applies contemporary cutting techniques. The result is a stone with more fire and brilliance than its antique cousin, whilst retaining those signature softly rounded corners. It is the most popular choice for couples who want the cushion shape with maximum sparkle.

The elongated cushion cut stretches the traditional square proportions into a rectangle, typically with a length-to-width ratio between 1.15 and 1.30. The effect is elegant and flattering on the hand, creating the illusion of longer fingers. An elongated cushion cut ring is a striking choice for those who want something distinctive without straying into unfamiliar territory.

Every cushion cut diamond carries the fingerprint of its cutter. That is what makes this shape so personal. No two stones catch the light in quite the same way, and that individuality is precisely why it belongs in a bespoke ring.

The Persian Connection: Cushion Cuts and Muqarnas Architecture

At Silux London, our tagline is "Persian Heritage, Silk Road Journey," and it is not simply a marketing phrase. Persian art and architecture genuinely inform every piece I design. The cushion cut holds a particular resonance for me because of its connection to one of the most beautiful elements in Persian building: the Muqarnas.

Muqarnas are the honeycomb-like vaulted structures you find adorning the ceilings of mosques, palaces, and bazaars across Iran, from the soaring domes of Isfahan to the intimate prayer halls of Shiraz. They are formed from interlocking geometric cells with softly rounded transitions, each one catching light from a slightly different angle, creating an effect that shifts and dances as you move beneath them.

The parallel to a cushion cut diamond is uncanny. Those gently rounded corners, those broad facets that break light into warm, shifting patterns: they echo the same geometric principles that Persian architects perfected over a thousand years ago. When I set a cushion cut stone in a Silux London ring, I am not just mounting a diamond. I am continuing a conversation between geometry, light, and craft that stretches back through the centuries along the Silk Road.

This is what draws me to the cushion cut above all other shapes. It is the meeting point between Eastern artistry and Western gemological precision, a stone that feels at home in both worlds.

Choosing the Right Cushion Cut Setting

The setting you choose for a cushion cut diamond will fundamentally shape how the stone presents on the hand. Here are the options I find work best, and what I typically recommend to my clients.

A four-claw solitaire is the purest expression of the cushion cut. It allows maximum light into the stone and lets the distinctive silhouette speak for itself. For old mine cuts with character and warmth, this is often my first recommendation. It is confident and unfussy.

A halo setting frames the centre stone with a border of smaller diamonds, adding presence and perceived size. For cushion cuts below 1.5 carats, a halo can be an excellent way to create visual impact without increasing your stone budget. It also works beautifully with elongated cushion cuts, accentuating their graceful proportions.

A bezel setting wraps a thin band of metal around the stone's perimeter, offering both security and a sleek, modern aesthetic. I have designed several bezel-set cushion cut rings in our Pasargad collection, and they have a quietly powerful presence on the hand.

Three-stone settings pair a cushion cut centre with two accent stones, often half-moons, trillions, or tapered baguettes. This is a classic format that adds visual narrative to the ring, with the side stones framing the cushion like chapters in a story.

For metal, I most often work in 18ct yellow gold or platinum. Yellow gold complements the warmth of cushion cut diamonds, particularly old mine cuts, whilst platinum offers a crisp, contemporary contrast. Rose gold sits beautifully between the two, adding a romantic quality that pairs naturally with the cushion's soft lines.

Bespoke Cushion Cut Rings at Silux London

Every bespoke cushion diamond ring I create at Silux London begins with a conversation, not a catalogue. I want to understand who you are, the story behind your relationship, and what you want this ring to represent. From there, I source the perfect stone and design a setting that is entirely yours.

Our Mehr collection, which means "love" in Persian, is our bridal line, and many of the pieces within it feature cushion cut centre stones. But even within Mehr, no two rings are alike. The beauty of bespoke is that your ring exists only for you.

Pricing for a bespoke cushion cut engagement ring at Silux London typically begins around �2,500 and can extend to �8,000 or more, depending on the stone and complexity of the design. Every ring is handcrafted in Britain, hallmarked, and delivered with full certification.

What I bring to every commission is not just technical skill, but a design philosophy rooted in cultural heritage. My training at Birmingham's School of Jewellery gave me the Western craft tradition. My upbringing in Iran gave me the aesthetic language of Persian art. The result is jewellery that carries meaning beyond the material.

What to Expect from the Bespoke Process

If you have never commissioned a bespoke ring before, the process is simpler than you might imagine. Here is how it works at Silux London.

1. Initial consultation. We speak by phone, video call, or in person. I listen. You share your ideas, inspirations, budget, and any details about your partner's style. There is no obligation and no pressure.

I work with trusted suppliers in Antwerp, Tel Aviv, and Mumbai, and every stone I recommend has been personally vetted. Whether you want an old mine cut with antique charm or a modern elongated cushion with maximum brilliance, I will find the right match.

3. Design development. I create detailed CAD renderings of your ring, drawing on my seven years of experience in jewellery CAD design. You will see your ring from every angle before a single gram of metal is touched. We refine together until every detail is perfect.
