Shape No. 07 · Marquise Brilliant Cut
Marquise Diamond
The Most Regal of All Cuts
The marquise diamond is the most dramatically elongated shape in the world of fine diamonds — a pointed oval whose origins lie in the court of the French monarchy and whose impact on the finger is unmatched by any other cut. It maximizes perceived carat size, creates the most pronounced slimming and lengthening effect on the hand, and carries a narrative of aristocratic grandeur that no other shape can claim. For the buyer who wants presence, the marquise delivers it absolutely.
'The marquise is the only diamond shape with a name derived from noble title — and everything about it communicates that heritage: length, drama, authority, and an aristocratic refusal to be modest.'
History
Origin & History of the Marquise Diamond
Of all the diamond shapes in this guide, the marquise alone can lay claim to a documented royal commission. According to the most widely cited account in diamond history, the marquise cut was created around 1745 at the personal order of King Louis XV of France, who commissioned a stone to be cut in the shape of the lips of his favorite mistress, Jeanne Antoinette Poisson — the Marquise de Pompadour. The name 'marquise' itself derives from this origin, referencing the noble title of the woman who inspired it. The shape is also sometimes called the 'navette' — the French word for small boat — in reference to the boat-like outline of its pointed oval silhouette.
Whether the specific legend of Louis XV's commission is historically documented or mythologized is a matter of some scholarly debate. What is certain is that the marquise shape developed within the French court jewelry tradition of the mid-eighteenth century and was associated from its earliest days with aristocratic elegance and grandeur. The pointed oval outline — long, dramatically elongated, tapering to sharp tips at each end — was understood to symbolize status and sophistication in a way that the broader, rounder shapes of the era did not.
The marquise's popularity has followed the broader cycles of diamond fashion — high during the Edwardian and Art Nouveau periods, which prized elongated silhouettes in all jewelry forms; lower during the geometric preferences of Art Deco; strongly revived in the 1970s and 1980s when large, bold diamond jewelry was fashionable; and present today as a consistently distinctive choice for buyers who want a shape that makes a statement without compromise.
From a technical perspective, the marquise is cut using the same 58-facet brilliant-cut architecture as the round, oval, and pear — adapted for the double-pointed elliptical outline. Like the oval and pear, it is susceptible to the bow-tie effect, and like the pear, it has two sharp pointed tips that require protective prong placement. It is a shape that demands excellent craftsmanship and careful selection — but rewards it with an extraordinary visual impact.
1745
According to tradition, King Louis XV of France commissions a diamond cut in the shape of the lips of Jeanne Antoinette Poisson, the Marquise de Pompadour — creating the first marquise cut diamond.
1800s
The marquise shape is embraced by European high jewelry, particularly in parures (matched jewelry sets) where the elongated silhouette works beautifully in necklace pendants, earrings, and brooch centerpieces.
1900 - 1910s
The Edwardian era's love of delicate, lacy jewelry and elongated forms sees the marquise at the height of its early-modern popularity, often set in platinum with fine milgrain and filigree detailing.
1970s - 80s
A bold revival of the marquise as a statement engagement ring shape, favored for its impressive face-up size and dramatic proportions during a decade that prized visible luxury above all else.
2020s
The marquise re-emerges as a sought-after alternative engagement ring shape, particularly among buyers who appreciate its historical narrative, maximum elongation, and its ability to make carat weight appear larger than any comparable shape.
Anatomy
The Anatomy of the Marquise Diamond
The marquise is structurally the most extreme of the brilliant-cut shapes — a fully double-pointed ellipse that pushes the facet arrangement to its limits at both tips. Understanding its anatomy helps explain both its exceptional visual impact and the care it requires in setting and evaluation.
Critical Optical Consideration
The Bow-Tie Effect in Marquise Diamonds
The marquise is the shape most severely prone to the bow-tie effect of all fancy cut diamonds. Because the marquise pushes its elongated proportions to an extreme, the central zone of the stone — where the two halves of the brilliant-cut pattern must meet across the widest section — is particularly susceptible to dark shadow formation. In the marquise, a severe bow-tie can be dramatic and deeply distracting. A good bow-tie — slight, present, but not dominant — can actually enhance the stone's visual depth by creating contrast. Evaluating bow-tie severity by eye is mandatory for any marquise purchase; it cannot be assessed from a grading report. Additionally, both pointed tips must be protected with V-prongs — unlike the pear, the marquise has two vulnerable points, doubling the structural consideration.
The two sharp pointed ends of the marquise — its most distinctive and most vulnerable features. Both tips are structural weak points requiring V-prong protection. The sharpness and symmetry of the tips are critical quality indicators: misaligned or blunt tips immediately betray poor cutting.
The widest section of the marquise at its mid-point. The belly width relative to the stone's length determines the length-to-width ratio. A narrow belly produces a dramatically elongated stone; a wider belly creates a shape closer to a flattened oval. Most well-regarded marquise diamonds have a belly that is about half the stone's length.
The curved sections on each side connecting the belly to the points. Wings should be gently and evenly curved on both sides — the marquise must be perfectly symmetrical from tip to tip and wing to wing. 'French tips' are a design variation where small star facets replace the bezel facets at the points, reducing the visibility of the V-prong.
The large flat facet on the crown, elliptical in outline. In a marquise, the table percentage interacts with the crown height to control the balance between brilliance and fire. Tables in the 53–63% range produce the most balanced light performance in this shape.
The perimeter edge of the marquise follows the pointed oval outline. Girdle thickness must be evaluated at both points — these are the thinnest areas and the most prone to chipping if the girdle is too thin. A girdle of Medium at the tips is the recommended minimum for daily wear.
The most defining proportion of the marquise. A ratio of 1.85–2.10 produces the classical marquise silhouette. Below 1.75, the stone reads as a wide, squat shape that loses the marquise's defining drama. Above 2.20, it becomes very narrow and the bow-tie tendency intensifies significantly.
Buying Guide
Expert Advice for Buying a Marquise Diamond
Evaluate the Bow-Tie and Symmetry Together
The marquise requires the most careful bow-tie evaluation of any shape. Because the length-to-width ratio is so extreme, the central zone of the stone is particularly prone to a severe, dark bow-tie shadow. View every marquise face-up in natural light and observe the centre — a slight bow-tie is acceptable and common; a bow-tie that dominates the centre of the stone is a serious optical flaw. Simultaneously evaluate symmetry: the two tips must align perfectly along the length axis, the wings must curve identically, and the belly must sit at the true midpoint. Asymmetry in a marquise is immediately apparent to any viewer.
Protect Both Tips With V-Prongs
Unlike the pear, which has one vulnerable pointed tip, the marquise has two. Both require dedicated V-prong protection for everyday wear. A standard rounded prong at a marquise tip provides inadequate coverage — the point extends beyond the prong and is exposed to impact. V-prongs cover the tip from both sides and are the industry standard for this shape. When commissioning a setting for a marquise, always specify V-prongs at both ends and request that the jeweler show you the coverage before the ring is finalized. An alternative is a full east-west bezel setting, which provides complete coverage of both tips and creates a strikingly modern aesthetic.
The Marquise Maximizes Face-Up Size More Than Any Other Shape
If carat weight efficiency — the ratio of face-up visual size to actual carat weight — is a priority in your purchase, the marquise outperforms every other diamond shape. Its extreme length-to-width ratio spreads its mass across the largest possible surface area, producing a stone that appears considerably larger than a round, cushion, or princess of the same carat weight. A 1.00ct marquise at an ideal ratio of 1.95 measures approximately 10.0 × 5.0mm — compared to 6.5 × 6.5mm for a 1.00ct round. This is the shape's single greatest practical advantage, and it is worth factoring into budget planning.
Consider the East-West Orientation
Traditionally, marquise diamonds are worn with the points running vertically — along the length of the finger — to maximise the elongating effect. In recent years, the east-west orientation — with the points running horizontally across the finger — has become a popular alternative, creating a dramatically different, more unusual aesthetic. East-west marquise rings are typically set in a bezel or with prongs at the belly rather than the tips, and the horizontal orientation produces a bold, contemporary look that many buyers find more wearable for everyday life than the traditional vertical placement. Discuss both orientations with your jeweler before committing to a setting design.

Shapes Related to the Marquise Diamond
The marquise without the pointed tips — same elongating effect, same brilliant-cut faceting, same bow-tie consideration, but with rounded ends that are more durable and easier to set. If the marquise's drama appeals but the sharp tips concern you, the oval is the natural next step.
The marquise with one rounded end — the pear trades the marquise's symmetry and extreme elongation for a directional teardrop silhouette. It shares the bow-tie characteristic and the V-prong tip requirement, but offers a more feminine, less regal aesthetic.
The marquise's structural and optical reference point — both share 58 facet brilliant-cut architecture. The round is the benchmark for light performance; the marquise extends and dramatizes that light pattern across a far greater surface area. Compare both when maximum sparkle is your priority.

Common Questions
Diamond Shape FAQ
Shape refers to the outline of the diamond as viewed from above — round, oval, pear, and so on. Cut refers to the quality of the craftsmanship: how well the diamond's facets are angled, polished, and proportioned. A round diamond with an Excellent cut grade has been faceted to precise ideal proportions. A round diamond with a Poor cut grade has the same shape but far inferior light performance. Both shape and cut matter; shape determines the diamond's silhouette, cut determines how beautifully it performs within that silhouette.
Elongated shapes — particularly the marquise, oval, and pear — tend to have the largest face-up appearance relative to their carat weight, because their mass is spread across a longer surface area. The emerald cut also reads as large due to its open table. The round brilliant, by contrast, concentrates mass into a compact depth, so a 1.00ct round will measure approximately 6.5mm across, while a 1.00ct oval may measure 8.0 x 5.5mm — appearing visibly larger in many settings.
The round brilliant is the most scientifically optimised shape for light return — its 58 facets are positioned according to precise mathematical principles that maximise brilliance, fire, and scintillation simultaneously. However, "best" is subjective. A well-cut oval, cushion, or radiant can be extraordinarily beautiful, and many buyers prefer the distinctiveness of a fancy shape over the conventional round. The most important factor is ensuring the cut quality is excellent, regardless of the shape you choose.
Round brilliant diamonds have historically held their resale value better than fancy shapes, largely because they represent the largest segment of market demand. Fancy shapes — ovals, pears, cushions — can fluctuate more in resale value depending on current trends. That said, diamonds are generally not considered liquid investment assets, and the intrinsic beauty and personal meaning of your chosen shape should take precedence over resale considerations in most purchasing decisions.
For round brilliants, the GIA and AGS provide cut grades (Excellent/Ideal) that reflect overall proportion quality. For fancy shapes, no equivalent standardized cut grade currently exists — which means buyers must evaluate proportions themselves. At Michael Gabriels, each of our individual shape guides includes a detailed proportions section with the specific measurements you should look for, and our gemologists are available to review any stone you are considering.
