Key Takeaways

• Royal History: The marquise diamond was commissioned by King Louis XV of France, inspired by the smile of his mistress, the Marquise de Pompadour.
• Flattering Shape: Its elongated form can make the wearer’s finger appear longer and more slender.
• Maximizes Size: The cut is designed to make the diamond appear larger per carat than many other shapes.
• Bow-Tie Effect: This cut is prone to a “bow-tie” shadow in the center, which can be minimized with a good cut.
• Vulnerable Points: The two pointed ends are delicate and require protective settings, like V-prongs.

What is a Marquise Diamond?

A marquise diamond is a type of modified brilliant cut. Think of it as an oval with two sharp points at each end. Its unique shape is sometimes called a navette, which is French for “little boat,” because it resembles the hull of a small ship. This cut is designed for maximum sparkle, featuring 58 facets that reflect light beautifully, similar to a round brilliant diamond.

What truly sets the marquise diamond apart is its impressive length-to-width ratio. This feature makes the stone look significantly larger than a round or princess-cut diamond of the same carat weight. For anyone looking to get a bigger look for their budget, the marquise diamond is an excellent choice. Its elongated shape not only enhances its own size but also has a flattering effect on the hand, making the finger appear longer and slimmer. This combination of historical romance, striking appearance, and visual value makes it a compelling option for those seeking something beyond the ordinary.

The Royal History and Origins

The story of the marquise diamond is steeped in 18th-century French royalty and romance. The cut was commissioned by King Louis XV, a monarch known for his love of the arts and lavish lifestyle. He was utterly enchanted by his chief mistress, Jeanne Antoinette Poisson, the Marquise de Pompadour. He wanted a diamond that would perfectly capture the shape of her enchanting smile.

In response, royal jewelers developed this unique, elongated cut with pointed ends, and it was named “marquise” in her honor. The title itself was a high rank in the French court, and soon, courtiers began wearing marquise-cut diamonds to signify their status. This legacy of aristocracy and passion has followed the marquise diamond through the centuries. Choosing this cut is like wearing a piece of a legendary love story. Its regal background adds a layer of depth and significance that few other diamond shapes can claim, making it a timeless symbol of elegance and devotion.

Understanding the Anatomy of a Marquise Diamond

To truly appreciate a marquise diamond, it helps to know its specific parts. Like other fancy-shaped diamonds, its anatomy is key to its beauty and sparkle. Understanding these elements will help you evaluate the quality of a stone and choose one that meets your standards.

Here’s a breakdown of the key components:

• Belly: This is the central, widest part of the diamond. The curvature of the belly is crucial for the stone’s overall shape and how it distributes light.
• Point: These are the two sharp ends of the diamond. The points are the most delicate part of the stone and must be well-formed and protected by the setting.
• Wing: The curved area between the belly and the point. The symmetry of the wings is vital for a balanced and visually pleasing appearance.
• Girdle: The thin edge that separates the top of the diamond (the crown) from the bottom (the pavilion). A girdle that is too thick or too thin can affect the diamond’s durability and appearance.
• Table: The large, flat facet on the very top of the diamond. It’s the “window” into the stone, allowing light to enter and reflect.
• Pavilion: The lower part of the diamond, below the girdle. The pavilion’s facets are responsible for reflecting light back up through the table, creating the diamond’s brilliance and fire.

The precise relationship between these parts determines the diamond’s overall cut quality and light performance. A well-proportioned marquise diamond will have symmetrical wings, a gracefully curved belly, and sharp, aligned points.

The 4Cs of a Marquise Diamond: A Detailed Look

The 4Cs (Cut, Color, Clarity, and Carat) are the universal standard for grading any diamond. However, their importance can vary slightly for a marquise diamond due to its unique shape.

Cut: The Most Important “C” for a Marquise

For a marquise diamond, cut is arguably the most critical factor. Unlike round diamonds, grading labs like GIA do not assign a standard cut grade to fancy shapes. This means you need to use your own judgment. A great cut will ensure brilliant sparkle and minimize the bow-tie effect.

What to look for:

• Symmetry: The two halves should be perfect mirror images. The points should align perfectly with each other. Asymmetry can make the diamond look unbalanced and off-kilter.
• Length-to-Width Ratio: This ratio defines the diamond’s silhouette. The classic ratio is around 1.85 to 2.0, creating a slender shape. A lower ratio (around 1.7) will look chubbier, while a higher ratio (above 2.1) will be very long and thin. The choice is a matter of personal preference.
• The Bow-Tie Effect: This is a dark, bow-tie-shaped shadow that can appear across the center of the diamond. It’s caused by facets that don’t properly reflect light. A slight bow-tie is nearly unavoidable in a marquise diamond, but a well-cut stone will have one that is minimal and not distracting. Avoid diamonds with a severe or dark bow-tie that dominates the stone.

Color: Finding the Sweet Spot

Color in a diamond refers to the absence of color. The GIA grades color on a scale from D (colorless) to Z (light yellow or brown). For a marquise diamond, color can be more noticeable near the pointed tips.

• Recommended Grades: For a stone that appears white, it’s best to stick with grades G, H, or I. These grades offer a great balance of beauty and value. A D, E, or F grade will be icier and colorless but come at a much higher price.
• Metal Choice: The color of your setting can also influence your choice. A yellow or rose gold setting can mask slight warmth in a diamond, meaning you could choose a J or K color grade and still have it look beautiful. For platinum or white gold, a higher color grade (G or H) is recommended to avoid a yellowish tint against the white metal.

Clarity: Hiding Imperfections

Clarity refers to the presence of internal flaws (inclusions) and external blemishes. The GIA clarity scale ranges from Flawless (FL) to Included (I3). The elongated shape and brilliant faceting of a marquise diamond are quite good at hiding minor inclusions.

• Eye-Clean is Key: You don’t need to pay for a flawless diamond. The goal is to find an “eye-clean” stone, meaning it has no inclusions visible to the naked eye. An SI1 or even a well-chosen SI2 can often be eye-clean.
• Inclusion Location: Pay attention to where the inclusions are located. Inclusions near the center table are more noticeable. Inclusions near the points or girdle are easier to hide and less of a concern. However, large inclusions near the delicate points can pose a durability risk.

Carat: Maximizing Size and Appearance

Carat is the measure of a diamond’s weight, not its size. However, carat weight directly impacts size. One of the biggest advantages of a marquise diamond is that its long shape makes it appear larger than other diamonds of the same carat weight.

A 1-carat marquise diamond has a larger surface area than a 1-carat round diamond, giving you more visual impact for your money. When choosing a carat weight, consider your budget and the finger size of the person who will be wearing it. Because the shape is so flattering, even a modest carat weight can look substantial on the hand.

The Bow-Tie Effect Explained

One of the most discussed characteristics of the marquise diamond is the “bow-tie” effect. This is a dark, bow-tie-shaped shadow that runs across the center of the stone. It’s not a flaw or an inclusion, but rather an optical consequence of the stone’s elongated cut. The facets in the center of the diamond are cut at an angle where they can block light rather than reflecting it back to your eye, creating a shadow.

Nearly every marquise diamond has a bow-tie to some degree. The key is to find one where the effect is minimal and doesn’t detract from the diamond’s overall beauty. A severe bow-tie will be very dark and prominent, creating a “dead” spot in the middle of the diamond. A slight bow-tie may only be visible from certain angles and can even add a bit of character. There’s no official grade for the bow-tie, so you must evaluate it visually. When shopping, ask to see the diamond in different lighting conditions to see how pronounced the bow-tie is.

Choosing the Ideal Length-to-Width Ratio

The length-to-width ratio of a marquise diamond determines its outline. It is calculated by dividing the diamond’s length by its width. This ratio dramatically affects the stone’s appearance, and the “ideal” ratio is largely a matter of personal taste.

• Classic Ratio (1.85 – 2.0): This is the traditional and most popular range. It creates a well-balanced, slender, and elegant silhouette that is neither too wide nor too narrow.
• Shorter Ratio (1.70 – 1.84): A marquise with a lower ratio will appear chubbier or more rounded. Some people prefer this fuller look, which can feel a bit more robust.
• Longer Ratio (2.01+): A higher ratio results in a very long, thin, and dramatic shape. This can be very striking but may also appear more fragile.

When choosing, think about the overall design of the ring and the preferences of the wearer. Looking at different ratios in person or through high-quality online videos is the best way to decide which outline you find most beautiful.

Popular Setting Styles for a Marquise Diamond

The right setting not only secures the marquise diamond but also enhances its beauty and unique shape. The most important consideration is protecting the two pointed tips, which are vulnerable to chipping.

Solitaire Setting

A solitaire setting is a timeless classic that puts the full focus on the marquise diamond. A six-prong setting is highly recommended, with V-shaped prongs (also called V-prongs) cradling the two points for maximum protection. A four-prong setting can also work but leaves the tips more exposed.

Halo Setting

A halo setting encircles the center marquise diamond with a ring of smaller diamonds. This adds a ton of extra sparkle and makes the center stone appear even larger. It’s a glamorous and popular choice that can turn a beautiful diamond into a breathtaking one.

Three-Stone Setting

In a three-stone setting, the marquise diamond is flanked by two smaller side stones. Popular choices for side stones include pear shapes, trillions, or smaller round diamonds. This style can symbolize the past, present, and future of a relationship and creates a very balanced, substantial look on the finger.

East-West Setting

A modern twist on the traditional vertical orientation, the east-west setting places the marquise diamond horizontally across the finger. This creates a unique, contemporary look that is very chic and unexpected. It’s a great choice for someone with a fashion-forward style.

Caring for Your Marquise Diamond Jewelry

Proper care is essential to keep your marquise diamond sparkling and safe for a lifetime. Due to its pointed ends, it requires a little extra attention compared to other shapes.

1. Protective Setting: The single most important step is ensuring the diamond is in a setting that protects its tips. V-prongs are the best option as they cover the points. Bezel settings, which encircle the entire stone in metal, offer the ultimate protection.
2. Regular Cleaning: Lotions, soaps, and everyday dirt can build up on the diamond, dulling its sparkle. Clean your jewelry regularly at home with a solution of warm water and a few drops of dish soap. Use a soft-bristled toothbrush to gently scrub behind the stone and in the setting.
3. Professional Check-ups: Take your ring to a professional jeweler at least once a year. They can check that the prongs are tight and secure and give it a thorough, professional cleaning.
4. Know When to Take It Off: Remove your marquise diamond ring before engaging in strenuous activities like sports, gardening, or heavy lifting. The points can snag on clothing or get hit, potentially causing damage. It’s also wise to take it off before swimming or cleaning with harsh chemicals.

Why Choose a Marquise Diamond?
