No shape in diamonds covers more finger per carat. The marquise is a brilliant stretched to two points, commissioned for a French court and built for drama, and it rewards the buyer who checks exactly two things: the bow-tie in its center and the prongs over its tips.
The marquise is a brilliant cut drawn out to a point at both ends, a boat-shaped outline the trade calls a navette. Legend ties its commission to the court of Louis XV and the Marquise de Pompadour, and the shape has carried that theatrical, aristocratic bearing ever since. Underneath the drama it runs the round brilliant's facet logic, scattering light across its full length.
Its defining talent is spread. The marquise is the most efficient shape in diamonds at converting carat weight into visible surface: a one carat stone stretches more than ten millimeters along the finger, out-measuring every classic shape at the same weight, and its taper elongates the hand the way no other outline can.
Like every elongated brilliant it carries a bow-tie, the dark band that can cross the center where the long facets meet, and it adds one concern of its own: two exposed points. Both are managed easily, the first by video review, the second by the setting, and neither appears on any certificate.
| Facets | Typically 57 to 58, brilliant style |
| Cut grading | No formal lab cut grade, evaluate by eye |
| Face-up size | The largest spread per carat of any shape |
| Length to width | 1.85 to 2.10 is the classic range |
| Relative price | Meaningfully below round per carat |
| Watch for | The bow-tie, point symmetry, and tip protection |
This is the marquise's home game. No shape faces up larger for its weight, and no shape elongates the finger more. Buyers who want maximum visible diamond for the budget end their search here, provided the stone passes its video review.
| Carat Weight | Typical Measurements | How It Wears |
|---|---|---|
| 0.75 ct | 9.5 x 4.7 mm | A slender flame, dramatic beyond its weight |
| 1.00 ct | 10.5 x 5.3 mm | Reads like a far heavier stone on the hand |
| 1.50 ct | 12.0 x 6.0 mm | Commanding length, unmistakable at a glance |
| 2.00 ct | 13.2 x 6.6 mm | A full sweep of the finger |
| 3.00 ct | 15.2 x 7.6 mm | Theatrical presence few shapes can match |
Measurements are typical for well proportioned stones. Individual diamonds vary with their cutting.
With no lab cut grade and two pointed tips at stake, the certificate opens the conversation on a marquise and the video finishes it. Here is where your attention belongs.
Every marquise carries some bow-tie where its long facets meet. On video, a good stone shows a soft shadow that flickers and travels as it moves; a poor one wears a fixed dark band across its middle. The difference never appears on paper, and it is the difference you will live with.
The two tips must align on the stone's long axis, and the curves on either side must mirror each other. Look also at the wings, the arcs between point and belly: flat wings make the stone look starved, bulged wings make it look heavy. Even, matching curves are the mark of a fine navette.
The tips concentrate both the stone's fragility and its color. Insist on a setting with V-prongs or shrouded claws covering both points, no exceptions, and hold color one thought higher than a round in the same metal, because warmth gathers where the stone narrows.
Every stone we recommend is scored by ROSI™, our gemological intelligence, built by our gemologists, and verified by a human eye before it reaches you. Request a ROSI™ Score Report on any diamond you are considering, ours or anyone else’s.

The marquise brings length and drama; the setting's job is to protect the points and decide the mood. These three directions cover most of what our clients choose, each made to order around your exact stone.
Four prongs on the belly, a V-prong guarding each point. The classic marquise mount: secure at the tips, minimal everywhere else, all length on display.
The navette turned sideways across the finger, modern and unexpected. The shape's drama becomes a horizon line, and the look belongs to buyers who chose deliberately.
Pavé tucked beneath the stone, invisible face-on, glinting in profile. Presence without touching the clean sweep of the outline.
The marquise gives you the most diamond your money can show. In exchange it asks for a video and a proper pair of prongs.
We will say it plainly: per carat of visible presence, nothing beats a marquise, and its price per carat sits well below the round's. The costs are specific and manageable. The bow-tie must be judged on video of the exact stone, because certificates are silent about it. The two points must live under V-prongs for life, because tips are where diamonds chip. And the wearer should love drama, because this shape does not do quiet. Meet those three terms and the marquise repays them every single day; skip the video or the prongs and you have bought the shape's reputation instead of its reward. Either way, we will tell you which stone you are looking at before you commit.

Our gemologists buy inside a written window, and decline outside it. These are those numbers, published in full, so you can hold any marquise to the same standard we do, including one you are considering somewhere else.
The marquise carries two points and the longest outline of any shape we stock, which makes symmetry the first thing to read. Both halves must mirror each other, and both points must align on the long axis.
Each scale shows the measurement range. Gold marks the RockHer Ideal window.
| Length to width ratio | 1.75 to 2.05 |
|---|---|
| Depth | 58% to 65% |
| Table | 56% to 65% |
| Girdle | Thin to thick |
| Polish | Very Good or better |
| Symmetry | Good or better |
| Culet | None |
Every diamond in our search carries these measurements on its report. In the filter panel, under RockHer’s Best, switch on Ideal Cut and the results narrow to the window above. Super Ideal Cut narrows them further still, to a tighter standard our gemologists hold diamond by diamond rather than publish as a range.
Nothing is hidden behind the switch. It applies the same numbers printed on this page.

Proportion is the first filter, not the last. A marquise can sit inside every range above and still be one we will not sell. These findings end a purchase in our office whatever the certificate says, and every diamond scored by ROSI™ is read against them by a gemologist before it is offered.
A certificate tells you what was measured. It does not tell you what was rejected.
Two marquise diamonds can carry the same carat, color, clarity, and grading laboratory, and one of them will never reach a client of ours. That gap is the work: reading the plot, the finish, and the face-up appearance against a written standard rather than against a price.
John Anderson, our Lead Gemologist, reviews marquises with clients every day. Send him the certificate of any stone you are considering and he will tell you what the paper says and what it leaves out. The consultation is complimentary and there is no obligation.
