Marquise diamond engagement rings are back in style across London in 2026 – and for good reason. Their sleek, elongated shape looks elegant, feels unique, and even makes fingers look longer. That’s why more couples are choosing this vintage cut over ordinary rounds.

At A Star Diamond, we’re seeing this revival every day. Ready to find out why London can’t get enough of the marquise? Let’s dive in.

What are the main reasons that make Marquise Diamond Rings trendy in 2026?

Marquise diamond rings are trending in 2026 for three simple reasons. First, Selena Gomez made them famous again. Second, the vintage shape looks fresh in modern settings like platinum and east-west styles. Third, London buyers want unique rings that aren’t round brilliants. It’s old-money elegance with a modern twist.

The Selena Gomez Influence

When Selena Gomez revealed her marquise engagement ring, social media did what social media does: searches surged overnight. Pinterest boards filled with marquise diamond rings. TikTok styling videos followed. But celebrity influence rarely creates a trend on its own — it accelerates one that was already building. The marquise was already returning before the announcement. Selena Gomez simply made it undeniable.

Vintage Meets Modern Luxury.

The marquise cut had its cultural peak in the 1970s and 80s. What has changed in 2026 is how buyers now want to wear it. The old heavy yellow-gold settings are gone. Today’s marquise diamond ring sits in clean platinum solitaires, minimal east-west mounts, and fine hidden halo designs. The shape is vintage. The setting language is entirely modern. That combination — old money elegance in a contemporary frame — is exactly what the 2026 buyer is looking for.

Why London Buyers Love Distinctive Ring Shapes.

London’s luxury jewellery buyers have always leaned toward individuality. A round brilliant is beautiful, but it is also everywhere. The marquise offers genuine exclusivity — an elongated diamond cut that is immediately recognisable, rarely seen on other fingers, and carries a history that most mainstream shapes simply do not have. For buyers who want their engagement ring to be uniquely theirs, the marquise is a natural choice.

The marquise has always been the choice of people who know exactly what they want — and in 2026, London buyers are remembering that.

What Makes a Marquise Diamond So Special?

Marquise diamonds offer history, value, and a unique look. They appear larger than their carat weight, cost less than round diamonds, and photograph beautifully. Here’s why they’re so special.

The History Behind the Marquise Cut

The marquise cut traces its origin to 18th-century France, commissioned by King Louis XV to reflect the shape of the Marquise de Pompadour’s lips. Its French name — navette, meaning little boat — describes the silhouette precisely: two pointed ends, a curved belly, a form that is inherently romantic and unmistakably royal. Very few diamond shapes carry a story like this one.

The Elongated Shape Creates a Larger Look

This is the most practical advantage of the marquise diamond: it appears significantly larger than its carat weight suggests. The elongated shape spreads surface area across the finger more efficiently than a round stone of identical carat. It also creates a finger-lengthening effect — one of the most flattering visual properties of any diamond shape. For buyers who want maximum visual impact per pound spent, the marquise delivers it.

A marquise diamond gives you more visible stone for your budget than almost any other cut. The shape works in your favour in ways the price tag doesn’t reflect.

Better Value Compared to Round Diamonds

Round brilliant diamonds carry a price premium because they are the most in-demand cut and because their manufacturing process wastes more rough stone. The marquise costs less per carat than a comparable round diamond while offering greater surface area and comparable brilliance. For London buyers seeking luxury without overpaying for convention, that value proposition is compelling.

Why Marquise Diamonds Photograph Better for Instagram and Pinterest

The elongated silhouette photographs exceptionally well. It fills a frame, catches directional light along its length, and reads as dramatic even in a casual snap. Gen Z brides in particular understand this intuitively — the marquise is the most social-media-legible of the fancy cuts, and on a platform like Pinterest or Instagram, that visibility matters.

Best Marquise Engagement Ring Styles Right Now

Marquise diamonds look beautiful in many settings. Here are the most popular styles in 2026 — from simple solitaires to vintage halos and east-west mounts. Pick the one that fits your personality.

Solitaire marquise rings represent the purest expression of the shape — nothing competing with the stone, nothing distracting from the silhouette. Clean, timeless, and effortlessly elegant.

Vintage marquise rings bring in halo settings, milgrain detailing, and Art Deco geometry. These work beautifully for buyers who want their ring to feel genuinely antique rather than merely vintage-inspired.

East-west marquise settings rotate the stone 90 degrees so it sits horizontally across the finger. It is the most fashion-forward way to wear the shape in 2026, and it is rising fast.

Hidden halo marquise rings add a concealed row of pavé diamonds beneath the centre stone — extra sparkle visible from certain angles, invisible from others. A genuinely luxurious detail.

Toi et Moi marquise rings pair the marquise with a second stone — oval, pear, or round — to create a two-stone design with personal meaning. Celebrity-driven but deeply individual in execution.

The diamond is the heart of the ring. The metal is its personality. Yellow gold for vintage warmth, platinum for lasting strength, rose gold for modern romance — choose the one that reflects her, not just the trend.

How to Choose the Perfect Marquise Diamond

A straight wedding band does not sit flat next to a marquise diamond ring. Instead, choose a curved or V-shaped band that fits snugly around it. You can also wear a thin diamond band next to your solitaire ring for a beautiful and trendy bridal look 2026.

Length-to-Width Ratio

The ideal ratio for a marquise diamond sits between 1.75 and 2.25. Below that range the stone looks stubby; above it, the shape becomes too narrow for its length. This proportion is what separates an elegant marquise from an awkward one.

The Bow-Tie Effect

Most marquise diamonds show a dark shadow across the centre, known as a bow-tie. In poorly cut stones, this shadow is distracting and permanent. In a well-cut marquise, it is minimal and adds depth rather than detracting from the stone. Always view a marquise in person before committing — a photograph will not show you the bow-tie accurately.

Clarity and Setting Protection

Inclusions near the pointed tips of a marquise are more visible than inclusions at the centre. VS2 or SI1 are reliable clarity grades for this shape, but tip placement matters — ask your jeweller to point out exactly where inclusions sit before you buy. V-prongs at both tips are essential; they protect the most vulnerable part of the stone from chipping during daily wear.

Best Wedding Bands to Pair With a Marquise Ring

A straight band rarely sits flush against a marquise. Curved bands and chevron bands are designed specifically to nest against the stone’s silhouette. Stacking a fine diamond band alongside a marquise solitaire is one of the most popular bridal combinations of 2026 — it adds brilliance without overpowering the centre stone.

Lab-Grown vs Natural Marquise Diamonds in 2026

Lab-grown marquise diamonds are chemically identical to mined stones and cost 60–70% less for the same carat and quality grade. For buyers who want a larger marquise diamond — and the elongated shape rewards size — lab-grown is an exceptionally strong option. The ethical sourcing argument is also significant: lab-grown diamonds carry no supply chain concerns.

The question is not which option is objectively better. It is which trade-off matters most to you — rarity and investment value, or size and sustainability.

Natural marquise diamonds retain the emotional weight of geological rarity. For buyers who see the ring as an heirloom, that distinction still matters. Both options, at A Star Diamonds, come with independent certification — GIA, IGI, or equivalent — because no stone should leave without one.

Why Marquise Diamonds Are Replacing Oval Rings in 2026

The oval had its moment — and a long one. But the 2026 luxury buyer is moving toward something less expected. The marquise offers the same finger-lengthening elegance as the oval, but with a sharper, more architectural silhouette that photographs differently and sits more distinctively on the finger. This is not a minor aesthetic shift; it reflects a broader move in bridal jewellery toward sculptural, personalised designs over mainstream safe choices.
