Marquise Diamond: Everything You Need to Know

With its elongated body and pointed ends, the marquise diamond is one of the most distinctive and dramatic cuts in the world of fine jewelry. Sometimes called the "navette" cut (French for "little boat"), this shape has adorned royal courts, vintage heirlooms, and modern engagement rings alike. If you're considering a marquise diamond, here's everything you need to know before you buy.

A Cut Born of Royalty

The marquise cut has one of the most romantic origin stories in jewelry history. In 18th-century France, King Louis XV commissioned a diamond cut to resemble the smile of his mistress, the Marquise de Pompadour. The resulting shape - an elegant ellipse tapering to a point at each end - became a favorite of the French aristocracy, and courtiers wore marquise diamonds to display their rank and refinement.

The cut saw major revivals in the Art Deco era of the 1920s and again in the 1970s and 80s, and today it's enjoying renewed popularity among buyers looking for something beyond the classic round brilliant.

What Defines a Marquise Diamond?

A marquise diamond (https://omjewelsinc.com/product/1-00-ct-i-vvs2-marquise-diamond-fancy-shape/) is a modified brilliant cut, typically featuring 58 facets arranged across its elongated, boat-shaped silhouette. Its defining characteristics include:

Two pointed ends that give the stone its dramatic profile and require protective settings.
An elongated body that maximizes visual size and creates a slimming effect on the finger.
Brilliant faceting that delivers the same fiery sparkle pattern as a round brilliant, adapted to the elongated shape.

Why Choose a Marquise?

It looks bigger than it is. Carat for carat, the marquise has one of the largest face-up surface areas of any diamond shape. A one-carat marquise can appear noticeably larger than a one-carat round brilliant, making it an excellent choice for buyers who want maximum presence for their budget.

It flatters the hand. The elongated shape draws the eye along the length of the finger, creating an elegant, lengthening effect that many wearers love.

It stands out. In a market dominated by round and oval stones, a marquise instantly signals individuality. It carries vintage charm while feeling fresh in contemporary settings.

It's often more affordable. Because demand for marquise diamonds is lower than for rounds, they typically cost 10–25% less per carat than a round brilliant of comparable quality.

What to Watch For When Buying

The bow-tie effect

Like other elongated cuts, marquise diamonds can display a "bow-tie" — a dark, bowtie-shaped shadow across the center of the stone caused by light leakage. Nearly all marquise diamonds show some degree of bow-tie, but in a well-cut stone it should be faint and unobtrusive. Always view the diamond in person or through high-quality video before purchasing, since certificates won't reveal the severity of a bow-tie.

Length-to-width ratio

The proportions of a marquise dramatically affect its appearance. The classic, most sought-after ratio falls between 1.85 and 2.10 — long enough to be elegant, but not so narrow that the stone looks like a sliver. Ratios below 1.85 appear shorter and wider; ratios above 2.10 look longer and thinner. There's no wrong answer here, only personal preference, but extreme ratios can amplify the bow-tie effect.

Symmetry

Symmetry is critical in a marquise. The two points should align perfectly with each other, and the two halves of the stone should mirror each other exactly. Even slight asymmetry in this shape can make the diamond look lopsided in its setting.

Protecting the points

The two sharp tips are the most vulnerable parts of a marquise diamond - they're prone to chipping if left exposed. Look for settings with V-shaped prongs (also called V-tips) that cradle and shield each point. The points are also where color and inclusions tend to concentrate, so inspect these areas closely.

Color and clarity

The brilliant faceting of a marquise hides inclusions fairly well, so many buyers find that a VS2 or even SI1 clarity grade looks eye-clean. Color, however, can be more visible at the tapered points where facets are smaller. If you're setting the stone in white gold or platinum, an H color or better is a safe choice; yellow or rose gold settings are more forgiving and pair beautifully with warmer stones.

Setting Styles That Shine

The marquise is remarkably versatile. Popular setting choices include:

Solitaire with V-prongs - a timeless look that lets the dramatic shape speak for itself.
Halo settings - a ring of small diamonds amplifies the stone's already impressive spread.
East-west orientation - setting the marquise horizontally across the band creates a modern, unexpected twist.
Vintage-inspired designs - milgrain detailing, filigree, and side stones complement the cut's aristocratic heritage.
Three-stone settings - flanking a marquise with tapered baguettes or pear-shaped side stones - enhance its regal profile.

Caring for a Marquise Diamond

Because of its exposed points, a marquise deserves a little extra care. Remove your ring during heavy manual work or workouts, have the prongs - especially the V-tips - inspected by a jeweler once a year, and clean the stone regularly with warm water, mild soap, and a soft brush to keep its brilliance at full strength.

Is a Marquise Diamond Right for You?

Choose a marquise if you want a stone with history, drama, and exceptional face-up size - and if you love the idea of wearing something that stands apart from the crowd. Just be diligent about cut quality: prioritize strong symmetry, a pleasing length-to-width ratio, and a minimal bow-tie, and insist on a protective setting for those elegant points.

Buy from a jeweler who provides certification from a reputable lab (such as GIA or IGI) along with high-resolution imagery or in-person viewing. With the right stone and setting, a marquise diamond delivers centuries of royal glamour in a shape that still turns heads today.
