Diamond Education

The marquise cut diamond is dramatic, elegant, and utterly distinctive. Often called a "navette" (French for "little boat"), it is one of the most eye-catching diamond shapes available today.

We'll cover everything you need to know before buying a marquise cut diamond—from understanding its fascinating history to evaluating cut quality, and tips to help you make a confident, informed choice.

Marquise Cut Basics

A marquise cut diamond is an elongated brilliant cut with pointed ends and curved sides, often described as eye-shaped or boat-shaped. The unique shape of this diamond cut gives it a distinctive and elegant appearance.

Despite its distinctive outline, the marquise is a brilliant-cut diamond. It does not have a standardized number of facets and typically features a faceting style similar to other brilliant cuts, designed to maximize light return, though the exact number of facets varies by cutting design.

When well cut, marquise diamonds display excellent sparkle, while their elongated shape draws the eye along the stone's length, creating a graceful, finger-lengthening effect.

History of the Marquise Cut

The marquise cut has one of the most romantic origin stories in diamond history. Legend holds that King Louis XV of France commissioned the cut in the 18th century to resemble the smile of his mistress, the Marquise de Pompadour. While this charming tale may be apocryphal, it captures the marquise's association with royalty, romance, and French elegance.

The marquise gained popularity throughout the Victorian and Edwardian eras. Its elongated, boat-like shape was considered highly fashionable and elegant, perfectly suited to the ornate jewelry styles of the period. The diamond shape was also practical—it maximized the diamond's surface area, creating an impressive visual impact.

It saw renewed interest in the mid-20th century, particularly in the 1960s and 1970s, when bold, expressive diamond shapes were in vogue. Today, marquise diamonds are experiencing a modern revival, embraced by those seeking vintage inspiration with contemporary edge—distinctive, expressive, and far from conventional.

Pros and Cons of Marquise Cut Diamonds

The marquise cut diamond offers a dramatic and distinctive alternative to traditional shapes. This has several benefits and potential limitations as highlighted below:

Pros:

• Maximum Visual Impact: Offers one of the largest surface areas per carat among diamond shapes, making the diamond look significantly larger.
• Most Elongating Shape: Creates the most dramatic finger-lengthening effect, making hands appear more slender and elegant.
• Unique and Distinctive: Highly recognizable boat shape stands out and makes a memorable impression—perfect for those wanting something different.
• Excellent Brilliance: When well-cut, sparkles beautifully with brilliant-cut faceting that rivals rounds in light performance.
• Significant Value: Costs 25–35% less than comparable rounds, offering substantial savings.
• Vintage Appeal: Historical connection to French royalty and 1970s glamour appeals to vintage enthusiasts.
• Versatile Orientation: Can be worn with points horizontal (traditional) or vertical (modern east-west setting) for different aesthetics.

Cons:

• Bow-Tie Effect: Almost all marquise diamonds show some degree of bow-tie—a dark shadow across the center. Finding one with minimal bow-tie requires careful selection.
• Vulnerable Points: Both pointed tips are prone to chipping and require protective V-prongs or bezel settings on both ends.
• Symmetry Critical: Any asymmetry in the curves or point alignment is immediately obvious and detracts significantly from beauty.
• Color Shows More: The elongated shape and pointed ends can show more color than rounds, requiring higher color grades.

Marquise Cuts vs. Other Diamond Shapes

Marquise cuts occupy a unique space among elongated fancy brilliant cuts. Here's how they compare to other diamond shapes:

• Compared to Oval Cuts: Marquises offer a more dramatic and distinctive silhouette with pointed ends, while ovals have a softer, more approachable outline.
• Compared to Pear Cuts: Both have a pointed tip, but the marquise has two points and a more symmetrical, boat-like shape.
• Compared to Round Diamonds: Marquises offer a far larger face-up appearance per carat and a more distinctive look, often at a significantly lower price.

Understanding the Bow-Tie Effect in Marquise Diamonds

The bow-tie effect is a common visual characteristic in elongated diamond shapes, including marquise cuts. It appears as a darker, shadow-like area across the center of the diamond, resembling the shape of a bow tie. This occurs when light leaks through the diamond rather than reflecting evenly back to the eye.

A minimal bow-tie is barely visible or only noticeable at certain angles and is acceptable in well-cut marquise diamonds. A moderate bow-tie is visible but doesn't dominate the diamond's appearance or significantly reduce brilliance. A severe bow-tie presents as a prominent dark band that detracts from beauty and brilliance—these stones should be avoided.

Because the bow-tie effect is not noted on certification reports, it must be evaluated visually. Always review high-quality videos or view the diamond in person to observe how light moves across the stone.

What to look for: marquise diamonds with excellent symmetry and even facet alignment. Avoid diamonds with overly shallow or deep proportions.

How to Choose a Marquise Cut Diamond

Cut Quality

Cut quality is an important consideration when choosing a marquise cut diamond. The cut determines brilliance, fire, and overall light performance.

Like other fancy shapes, marquise cuts don't receive an official cut grade from GIA. However, specific proportion guidelines indicate superior light performance:

Recommended Guidelines:

• Depth: 58%–62%
• Table: 53%–63%
• Symmetry: Very Good to Excellent
• Polish: Very Good to Excellent

Symmetry is absolutely crucial for marquise diamonds—more so than any other shape. The two points must align precisely along the centerline, and the wings (curves on each side) should mirror each other. Always review videos from multiple angles to assess symmetry, check for bow-tie effect, and ensure even light return across the diamond.

Length-to-Width Ratio

The length-to-width ratio dramatically affects a marquise's appearance.

Wider marquises (1.75–1.85) offer fuller wings and a less elongated look. Classic marquises (1.85–2.00) deliver the most traditional and popular proportions. Elongated marquises (2.00–2.15) create a slender, dramatic appearance, while very elongated ratios (2.15–2.25) offer the most dramatic finger-lengthening effect.

Most buyers prefer ratios between 1.85 and 2.20, which provide the classic marquise silhouette with balanced proportions. The choice depends entirely on your personal aesthetic preference.

Clarity

Marquise diamonds offer moderate ability to hide inclusions. While their brilliant faceting helps mask some imperfections, the elongated shape can make certain inclusions more visible, particularly those located near the center or under the table.

For most buyers, VS2–VS1 diamond clarity grades offer the best balance of beauty and value. They are typically eye-clean while being significantly more affordable than VVS grades. Well-chosen SI1 stones can also work, depending on inclusion type and placement.

Important: Avoid marquise diamonds with inclusions located at or near the pointed tips, as these create weak points that increase the risk of chipping.

Color

Marquise diamonds tend to retain color more noticeably than round brilliants, particularly at the pointed ends where facets concentrate color. We recommend diamond color grades G–H or higher for platinum or white gold settings to achieve a bright, icy appearance. For yellow or rose gold, I-J grades work beautifully, matching the warmth of the metal and offering significant savings.

Carat Weight in Marquise Diamonds

One significant advantage of marquise cuts is their exceptional face-up size. Marquise diamonds typically appear 15–20% larger than round diamonds of the same carat weight due to their elongated shape and large surface area. This means a 1-carat marquise can look as large as a 1.20-carat round, giving tremendous visual impact without increasing budget.

Best Settings for Marquise Cut Diamonds

The marquise cut diamond looks striking in a variety of settings. The list below shows some of the most popular settings that pair beautifully with this elegant diamond.

Halo Settings: Very popular with marquise cuts. Halos of micro-pavé diamonds surround the center stone, adding sparkle and making it appear even larger while protecting the vulnerable points.

Solitaire Settings: A marquise cut in a solitaire setting allows the unique shape and elegance of the stone to really shine. Six-prong settings protect the tips and provide maximum security.

East-West Settings: Mounting the marquise horizontally creates a modern, fashion-forward look that's increasingly popular—a bold alternative to the traditional vertical orientation.

Famous Marquise Cut Jewelry

The marquise cut has a storied history in high-profile jewelry. Its origins are famously linked to King Louis XV of France, who reportedly commissioned the shape in honor of his mistress, the Marquise de Pompadour—giving this diamond cut an enduring association with romance and royalty. In modern times, the marquise has appeared on the fingers of notable celebrities and style icons, celebrated for its dramatic elongation and vintage glamour. Beyond engagement rings, marquise diamonds shine in pendants and earrings, where their distinctive boat-shaped outline creates a bold, eye-catching statement in both classic and contemporary designs.

Buying Tips

Keep these tips in mind if you're buying a marquise cut diamond to get the best quality:

• Check symmetry carefully. Ensure the two pointed ends of the stone are well aligned and the wings mirror each other precisely—poor symmetry is immediately noticeable once the diamond is set.
• Evaluate bow-tie visibility. View multiple videos and images from different angles and lighting to ensure the bow-tie is faint and minimal before making a decision.
• Choose a protective setting. Six-prong and bezel settings help protect the diamond's pointed tips from chipping.
• Insist on certification. Buy from a reputable jeweler experienced with fancy shapes and always request a diamond grading certificate.
