People who choose a marquise tend to know exactly why. It is not the safe shape, and it is not the most common one I make. But it gives you more visible diamond per carat than anything else, and on the hand it reads long, confident, and a little unexpected. If you are considering one, this is what I would tell you across the bench.
What a Marquise Diamond Is
A marquise is a brilliant cut shaped like a narrow ellipse that comes to a point at both ends. It carries about the same facet pattern as a round, so it has real sparkle, but it stretches that sparkle along the finger. The shape goes back to eighteenth-century France, had a big moment in the 1970s, and today looks modern again, especially on a thin band or set east-west across the finger.
How Big a Marquise Looks
This is the reason most people end up here. A 1 carat marquise measures about 10×5mm. A 1 carat round measures about 6.5mm, and a 1 carat oval about 8×5.7mm. Of the seven shapes I work with, the marquise has the largest face-up spread for the weight, because it spreads its carats lengthwise rather than carrying them in depth. If you want the most visible diamond for your budget, start here. For a side-by-side of every shape, see our guide on carat versus face-up size.
The Right Length-to-Width Ratio
Ratio is length divided by width. For a marquise, most people find 1.85 to 2.10 balanced, and 2.00 is the safe middle, which is exactly what a 10×5mm stone gives you. Below 1.85 the stone looks short and wide. Above 2.10 it becomes very slender and dramatic. Neither is wrong; it depends on your hand. Longer fingers carry a slender marquise well, while a slightly fuller ratio flatters shorter fingers.
The Bow-Tie Effect
Almost every marquise shows a bow-tie: a darker band across the center, where the stone is widest and the facets return less light. How strong it looks depends entirely on the cut, and it never appears on a grading report. That is why I look at every marquise face-up at the bench before it goes into a setting, instead of buying to the paperwork alone. A mild bow-tie adds contrast; a heavy one looks like a shadow.
Protecting the Two Points
The points are the thinnest edges of the stone and the most exposed to knocks. Uncovered, they can chip. Covered, they are not a concern. Every marquise I set gets a V-prong over each tip, which wraps the point in gold so the metal takes the impact instead of the diamond. I set those two prongs before anything else on the ring, because they are the ones that matter most.
Settings That Suit a Marquise
A solitaire lets the shape speak for itself and is the cleanest way to show off its length. A three-stone setting with round side stones softens the points and adds width, and it is one of my favorite ways to wear the shape; see our three-stone engagement rings. A thin band of 1.5mm or 2mm exaggerates the length even further by contrast; browse our thin band engagement rings. And an east-west setting, with the stone running across the finger, is the most modern take.
Choosing a Wedding Band
A straight band only sits flush with a low marquise setting. For most marquise rings, a contoured or V-shaped band that nests around the point is the better pairing. Because both rings are made to order, I shape the band to your engagement ring and size them together.
Grades Worth Paying For
Cut matters most, because it controls both sparkle and the bow-tie. Our Lab-Grown Diamonds are D to F color and VS clarity or better, and every stone 1 carat and above comes with an IGI report so the grades are on paper.
