Short answer: A marquise cut diamond is a long, boat-shaped brilliant cut with two pointed ends. It looks larger than any other shape of the same carat weight and makes fingers look longer and slimmer. When you buy one, look for a length-to-width ratio between about 1.75 and 2.25, good symmetry so both halves match, a mild bow-tie at most, and V-prongs or a bezel that protect the two points.
The marquise cut has a look you recognize from across the room: a slim, elongated stone that tapers to a point at each end. It has a long history, a strong vintage feel and some very practical advantages, especially if you want a diamond that looks big for its weight.
It is also a shape that rewards careful buying. The points need protection, the proportions matter more than with a round, and the "bow-tie" shadow can make or break a stone. This guide covers everything you need to know: where the marquise came from, how it differs from other shapes, how to judge quality, which settings suit it, and how to look after it for life.
Overview
A marquise cut diamond has a long, oval-like body with pointed ends, a shape often described as a boat, an eye or a grain of rice. It is a modified brilliant cut, which means it uses the same kind of triangular and kite-shaped facets as a round brilliant, rearranged to suit the elongated outline. The result is plenty of sparkle across the whole stone.
Because the marquise is long and fairly shallow, more of its weight sits in the visible top surface rather than hidden in the depth. That is why a marquise usually has the largest face-up area of any popular shape at the same carat weight. It is a favorite for engagement rings, east-west set rings, cluster designs, earrings and pendants.

Where Marquise Cut Diamonds Originated
The marquise shape is linked to 18th-century France. According to the popular story, King Louis XV wanted a diamond cut to resemble the lips of the Marquise de Pompadour, his companion and an influential figure at court. Whether or not every detail of the story is true, the name stuck, and the shape has been associated with royalty and refinement ever since.
Development: Cutting methods have improved a great deal since then. Early marquise stones were cut by eye, so their outlines and facets were often uneven. Modern cutting allows much more precise symmetry, which gives today's marquise diamonds brighter, more even sparkle. The shape has moved in and out of fashion over the years, and it is now popular again with people who like vintage-inspired or nature-inspired rings.
Symbolism: Because of its royal French connection, many people see the marquise as a symbol of luxury, confidence and individuality. It is a shape for someone who does not want to look like everyone else.
Name variations: You may also hear the marquise called a "navette", which is French for "little boat". It is the same shape.
What Makes the Marquise Shape Special
Shape and facets: A marquise usually has around 56 to 58 facets arranged in a brilliant pattern. That facet arrangement spreads light across the long body, so a well-cut stone sparkles from tip to tip.
Looks bigger for its weight: The long outline and relatively shallow depth mean a marquise faces up larger than a round, oval or princess of the same carat weight. If you want the most visible size for your budget, this is one of the strongest choices.
Flattering on the hand: Set north-south (pointing along the finger), the length of a marquise draws the eye along the finger, making it look longer and slimmer. This works well on shorter or wider fingers.
A distinctive look: Rounds, ovals and cushions are everywhere. A marquise stands out immediately and gives even a simple solitaire a strong personality.
The bow-tie effect: Like other elongated brilliant shapes, a marquise can show a darker band across the middle, shaped like a bow-tie. A small, soft bow-tie gives contrast and is normal. A large, very dark one makes the center look dead. A well-cut marquise keeps it mild so the sparkle looks even across the stone.
Versatile in settings: The marquise works in simple solitaires, halos, three-stone rings, east-west designs, cluster rings and leaf or vine designs. Smaller marquise stones are also used as accents beside a larger center stone.
Marquise vs Other Elongated Shapes
Many buyers compare the marquise with oval and pear, since all three look large for their weight and lengthen the finger. Here is how they differ.
| Shape | Outline | Look | Care point |
|---|---|---|---|
| Marquise | Two pointed ends | Vintage, bold, very long | Protect both points |
| Oval | Rounded ends | Soft, elegant, classic | No points to protect |
| Pear | One rounded end, one point | Romantic teardrop | Protect the single point |
| Dutch marquise | Pointed ends with a faceted, angular body | Unique, antique-inspired | Protect both points |
If you love the length of a marquise but want something gentler, an oval is the natural alternative. If you want the drama of a point with a softer side, consider a pear. If you want the marquise outline with a more unusual faceting style, look at our Dutch marquise jewelry.
Marquise Cut Diamond Purchase Advice
The 4Cs (cut, color, clarity and carat) apply to every diamond, but a marquise has a few extra details to check. Work through these in order.
1. Cut quality and symmetry
Cut matters most with a marquise. Grading reports for fancy shapes do not usually give an overall cut grade the way they do for rounds, so you need to judge it from the stone, the photos or video, and the polish and symmetry grades. Look for:
- Matching halves: Draw an imaginary line down the length and across the width. Both sides should mirror each other, and the two points should line up.
- Even "wings": The curved sides should have a smooth, balanced curve, not one side flatter than the other.
- Mild bow-tie: Some darkness in the center is normal. Avoid stones where the bow-tie is large and black in every photo.
- Good polish and symmetry grades: Very Good or Excellent on the report is a reliable sign of careful cutting.
2. Length-to-width ratio
The length-to-width ratio is the length of the stone divided by its width. For a marquise, most people find the most balanced look somewhere between 1.75 and 2.25. A lower ratio gives a wider, fuller stone. A higher ratio gives a slimmer, more dramatic stone. Personal taste comes first, so look at a few ratios on the hand before deciding.
| Ratio | Appearance | Suits |
|---|---|---|
| Below 1.75 | Short and wide | Those who want a softer, fuller outline |
| 1.75 to 2.00 | Balanced, classic marquise | Most engagement rings |
| 2.00 to 2.25 | Long and slender | A dramatic, elegant look; longer fingers effect |
| Above 2.25 | Very thin | Accent stones and fashion designs |
3. Color
Color can gather in the points of a marquise, where light travels a shorter path. If the points look slightly yellow while the center looks white, the stone can appear uneven. For a bright white look in white gold or platinum-colored metal, G or better is a safe choice. In yellow or rose gold, a slightly lower color grade often looks fine because the warm metal hides a faint tint.
4. Clarity
A marquise has a large, open face, so inclusions near the center can be easier to see than in a round. Look for an eye-clean stone, which in most cases means VS2 or better, though some SI1 stones are clean to the eye. Pay special attention to the points. A feather or crack close to a tip can make that tip more likely to chip, so avoid inclusions there even if they are tiny.
5. Carat weight
Because a marquise faces up large, you can often choose a slightly lower carat weight and still get the size you want on the hand. Compare stones by their millimeter measurements as well as their weight, since two stones of the same carat weight can look different sizes depending on their proportions.
6. Setting
The two points are the most vulnerable part of a marquise. Choose a setting that covers them, such as V-shaped prongs at each tip or a full or partial bezel. A six-prong setting with V-prongs at the ends and two prongs on the sides is a common, secure choice.
7. Certification
Ask for a grading report from a respected independent laboratory. For lab grown diamonds, IGI and GIA are the names you will see most often. The report confirms the stone's identity and lists its measurements, color, clarity, polish and symmetry, so you know exactly what you are paying for. Many Ivevar lab grown diamonds come with an IGI certificate.
Tip: Always ask to see a marquise in a video, not just a photo. The bow-tie and the evenness of the sparkle are much easier to judge when the stone moves.

Lab Grown Diamond or Moissanite in a Marquise Cut?
Both stones are available in marquise cuts, and both make beautiful rings. The choice depends on what you value most.
- Lab grown diamond: A real diamond, chemically, physically and optically the same as a mined diamond. It scores 10 on the Mohs hardness scale and has the classic white sparkle of diamond. Lab diamonds are grown using the CVD or HPHT method and graded by labs such as IGI and GIA. Browse our lab diamond marquise jewelry.
- Moissanite: A different gemstone, not a diamond. It scores 9.25 on the Mohs scale, which makes it very durable for daily wear. Its refractive index is about 2.65 compared with about 2.42 for diamond, so it shows more colorful, rainbow-like flashes. It is usually the more budget-friendly option. See our moissanite marquise collection.
Whichever you choose, the buying rules in this guide still apply: check the ratio, the symmetry and the setting.
Best Settings for a Marquise Diamond
The right setting protects the points and shows off the length. These are the most popular choices.
- Solitaire: A single marquise on a slim band lets the shape speak for itself. Make sure the setting has V-prongs at the tips.
- Halo: A ring of small stones around the marquise adds sparkle and makes the center look even larger. The halo also shields the points from knocks.
- Three stone: A marquise center with round, pear or tapered baguette side stones creates a balanced, elegant ring.
- East-west: Setting the marquise sideways across the finger gives a modern, unexpected look.
- Nature-inspired: Marquise stones look like leaves or petals, so they suit vine, leaf and floral designs. See our nature-inspired engagement rings.
- Bezel: A metal rim around the whole stone offers the most protection and a clean, modern look, ideal for an active lifestyle.
Choosing the metal
White gold makes a white diamond look icy and bright. Yellow gold gives a warm, vintage feel that suits the marquise's history. Rose gold adds a soft, romantic tone. Ivevar crafts rings in 10K, 14K and 18K gold. Higher karat gold has a richer color, while 10K and 14K are a little harder and more resistant to everyday wear.
How to Look After Marquise Cut Diamonds
Diamond is the hardest natural material, but hardness is not the same as toughness. A sharp blow at the right angle can still chip a point. A little care keeps your marquise looking its best for decades.
Clean it routinely. Soak the piece in warm water with a few drops of mild dish soap for 15 to 20 minutes, then scrub gently with a soft toothbrush, paying attention to the underside of the stone where lotion and soap build up. Rinse and dry with a lint-free cloth.
Get an expert inspection. Once a year, have a jeweler check the prongs, especially the ones at the tips. Prongs wear thin over time, and catching this early keeps the stone safe.
Store it carefully. Keep your marquise in a soft pouch or a lined jewelry box with separate sections. Diamonds can scratch other jewelry, and other diamonds can scratch them.
Limit strong chemicals and hard work. Take your ring off for gardening, gym sessions, heavy lifting and cleaning with bleach or other strong chemicals. Chemicals can dull or weaken the metal, and knocks are the main risk to the points.
Watch for snags. If the ring starts catching on clothing or hair, a prong may have lifted. Stop wearing it and have it checked.

Common Mistakes to Avoid
- Buying on carat alone: A heavy marquise with poor proportions can look smaller and darker than a lighter, well-cut one.
- Ignoring the bow-tie: A strong bow-tie is the most common reason a marquise looks disappointing in person.
- Unprotected points: A setting with round prongs at the tips leaves the most fragile part of the stone exposed.
- Choosing a ratio without seeing it: The difference between 1.8 and 2.2 is very visible on the hand. Look at both before deciding.
- Skipping the report: Without a grading report, you cannot be sure of the color, clarity or measurements.
Conclusion
The marquise cut combines royal history, a shape unlike any other and real practical advantages: more visible size per carat and a flattering, finger-lengthening effect. To get a beautiful one, focus on symmetry, a ratio you love, a mild bow-tie, clean points and a setting that protects both tips. Get those right and a marquise will look striking for a lifetime.

Q2: Why are marquise cut diamonds historically important?
The shape is named after the Marquise de Pompadour. According to the popular story, King Louis XV of France wanted a diamond cut to resemble her lips, which is why the marquise has long been linked with royalty and luxury.
Q3: What are the benefits of marquise cut diamonds?
A marquise looks larger than most shapes of the same carat weight, makes fingers look longer and slimmer, suits many setting styles and has a distinctive, elegant look.
Q4: What should I consider when buying a marquise cut diamond?
Check the symmetry, the length-to-width ratio (about 1.75 to 2.25 for a classic look), the bow-tie, color and clarity (especially near the points), a protective setting and a grading report from a respected lab such as IGI or GIA.
Q5: How do I care for my marquise cut diamond?
Clean it regularly with warm soapy water and a soft brush, have the prongs checked once a year, store it separately from other jewelry, and remove it for heavy work or when using strong chemicals.
Q6: Are marquise diamonds more likely to chip?
The two points are the most vulnerable part of the stone. Diamond is very hard, but a sharp knock on an unprotected point can chip it. V-prongs or a bezel at the tips greatly reduce this risk.
Q7: What is the bow-tie effect?
It is a darker band across the center of some elongated stones, shaped like a bow-tie. A slight bow-tie is normal. A large, dark one reduces sparkle, so compare stones in video before you buy.
Q8: Is a marquise a good choice for an engagement ring?
Yes. It is an unusual, eye-catching choice that gives you a lot of visible size for the carat weight. Just make sure the setting protects the points so the ring is comfortable for daily wear.
Q9: Is moissanite a type of diamond?
No. Moissanite is a separate gemstone made of silicon carbide. It is very hard (9.25 on the Mohs scale) and has more colorful sparkle than diamond, and it is available in marquise cuts too.
