Marquise cut diamonds are having a genuine moment in 2026, and for once the hype is earned. This elongated, pointed silhouette is one of the oldest cuts in the book, yet it looks strikingly current on the hand this year.

After a decade dominated by the round brilliant, couples are reaching for shapes with more personality. The marquise, sometimes called the navette, sits right in the sweet spot: vintage in pedigree, modern in effect, and unusually generous with the way it spreads across the finger. Before you shop, it helps to understand what actually separates a beautiful marquise from a mediocre one, because with this cut the details matter more than almost any other shape.

Those numbers set the scene. According to The Knot 2025 Real Weddings Study, 61 percent of US couples now choose a lab-grown center stone. As CNBC reported from the same data, average ring spend settled near $4,600, while National Jeweler notes the average center stone has grown to about 1.9 carats. Lab-grown value is exactly why an elongated, high-impact shape like the marquise feels within reach now.

Why Marquise Cut Diamonds Are Trending in 2026

Marquise cut diamonds are trending in 2026 because elongated shapes have overtaken the round brilliant as the most-requested silhouette, and the marquise leads the sharp-tipped end of that family. The Natural Diamond Council describes the marquise as a shape prized for its lengthening effect on the finger and its regal, vintage character. Celebrity influence sealed the revival. Jewelry historian Marion Fasel told National Jeweler, "Things kind of have to percolate in the market for people to be interested in them. Marquises were out there and then Selena locked it in."

The practical appeal is just as strong. Because a marquise carries much of its weight across a long, flat plane, it presents a larger face-up surface than a round diamond of the same carat weight. That means visible presence without paying for a heavier stone, a logic that pairs naturally with lab-grown pricing.

How to Judge a Marquise Cut Diamond

Judging a marquise cut diamond comes down to five things: length-to-width ratio, symmetry, the bowtie, the tips, and the setting. Get these right and even a modest carat weight looks refined and deliberate. Here is the framework we use on the bench at Roomy's Jewelery.

• Length-to-width ratio. The classic marquise ratio runs from 1.85 to 2.10. Nearer 1.85 looks fuller and softer; nearer 2.10 looks longer and more dramatic.
• Symmetry. The two pointed tips must line up on a single axis. If one tip sits off-center, the stone will look tilted set into a ring.
• The bowtie. Every marquise shows some dark shadow across the middle. A faint bowtie is normal; a heavy black band across the center is a cutting flaw.
• The tips. The two points are the most fragile part of the diamond and need protective prongs.
• The setting. East-west orientation and slim bezels are the defining 2026 looks for this shape.

Shape confidence grows once you see the marquise across different pieces. The Celeste Marquise Diamond Drop Earrings (from $450) show the classic pointed silhouette in a wearable everyday form, while the Liquid Diamonds Marquise Flow Pendant (from $250) frames a single marquise in sculpted solid gold. A marquise stud also makes a striking accent in a curated diamond ear stack. Every stone is lab-grown and backed by IGI and Roomy's certification.

Marquise vs Other Elongated Diamond Shapes

The marquise is one of three elongated shapes leading 2026, alongside the oval and the pear, and each flatters the finger differently. The table below compares them on the traits buyers ask about most, so you can decide which lengthening effect suits you before you commit.

If you want the fullest read on the two nearest alternatives, our oval cut diamond buyer's guide and our pear cut diamond guide break down ratios and settings in the same detail.

Settings, Metals and Real Prices

The best marquise settings in 2026 protect the tips while showing off the length, and solid gold is the honest foundation for all of them. East-west bezels, slim solitaires and cluster designs all suit the shape. For a soft-glamour take, the Marquise Diamond Cluster Pendant (from $1,200) arranges several marquise stones into a cascading drop, and the Halo Diamond Circle Pendant (from $1,500) rings marquise diamonds into a continuous open circle.

On metal, choose 14kt for the best balance of durability and warmth, 18kt for a richer color, or 10kt for the most accessible entry into solid gold. Whatever you pick, the point of buying lab-grown, as tracked by Statista, is that today's pricing lets you choose a larger, better-cut marquise for the same budget you once spent on a smaller stone.
