The world of diamonds is a dazzling array of light and geometry, but few cuts possess the romantic history and instantly recognizable silhouette of the Marquise cut. Exquisitely enchanting and steeped in royal lore, the Marquise is a shape that commands attention, offering a unique blend of classic elegance and dramatic flair. This comprehensive guide will delve into everything you need to know about this captivating cut, from its origins in the French court to how to choose the perfect one for your finger.

A Royal Beginning: The History of the Marquise Cut

The Marquise diamond’s story begins not in a gemological lab, but in the opulent court of King Louis XV of France around 1745. As legend has it, the Sun King commissioned his court jeweler to create a diamond shape that would perfectly mimic the alluring smile of his favourite mistress, Jeanne Antoinette Poisson, the Marchioness Madame de Pompadour.

Thus, the "Marquise" cut was born, a name derived from her title. This origin story imbues the stone with an undeniable sense of romance and luxury. Initially, these stones were cut in a style more akin to what we would now call a "boat-shaped" rose cut. Over centuries, the cut evolved with technology and taste, culminating in the brilliant-cut version we adore today, which saw a massive surge in popularity during the glamorous 1960s, 70s, and 80s. For a deeper dive into the history of diamond cuts, resources from the Gemological Institute of America (GIA) are invaluable.

Technical Specifications: Anatomy of a Marquise (Navette) Diamond

The Marquise, also known as the ‘Navette’ (French for "little ship"), is a fancy brilliant cut. Its elongated form, which tapers to points at both ends, is its most defining characteristic.

Facet Structure: Like the Round Brilliant, the modern Marquise brilliant cut is typically composed of 57 facets (33 on the crown, 24 on the pavilion). This intricate arrangement is designed to maximize the diamond's two most important properties: fire (the dispersion of light into rainbow colours) and brilliance (the return of white light to the eye). However, unlike the round brilliant, the pavilion of a Marquise can vary, having 4, 6, or 8 main facets.

The Cut Advantage: The elongated shape provides a significant benefit during the cutting process. It allows the diamond cutter to preserve more of the original rough diamond crystal than is typically possible with a Round Brilliant cut. Furthermore, its length and curved sides create a powerful illusion of greater size, maximizing the perceived carat weight. This makes the Marquise an stunning and often more economical choice for those seeking a larger-looking center stone.

Understanding Marquise Cut Grading

Unlike Round Brilliant diamonds, there are no universally accepted cut grading standards for fancy shapes like the Marquise. Major certifying laboratories like GIA provide clarity, color, and carat grades but do not issue a cut grade for Marquise diamonds. Therefore, the evaluation of cut quality falls to individual retailers.

At CaratX, we have developed our own rigorous criteria to ensure consistency and quality across all our Marquise offerings. Our grading takes into account critical proportions that directly impact the stone's beauty:

Grade Table % Depth % Length-to-Width Ratio

Excellent 55% - 62% 58% - 64% 1.95 - 2.05

Very Good 53% - 64% 57% - 66% 1.85 - 2.15

Good 52% - 65% 56% - 68% 1.75 - 2.25

Fair 50% - 70% 46% - 71% 1.65 - 2.30

Poor <50% or >70% <46% or >71% <1.65 or >2.30

Depth Percentage: This is perhaps the most critical factor. Because of their length, Marquise diamonds require adequate depth (58%-64% is ideal) to act as a prism, refracting light correctly from one facet to another and back out through the crown to your eye. A stone that is too shallow (low depth percentage) will allow light to leak out of the bottom (pavilion), creating large, unattractive dark areas and making the diamond appear lifeless and dull.

Table Percentage: The size of the top, flat facet (the table) relative to the diamond's width influences how light enters and exits. An overly large table can kill brilliance, while a very small one can make the stone look dark.

Polish and Symmetry: These grades, provided by labs like GIA, indicate the precision of the craftsmanship. Polish refers to the smoothness of the facet surfaces, while Symmetry refers to the precision of their alignment and the overall shape balance. Higher grades (Excellent/Ideal) are essential for optimal light performance.

Length-to-Width Ratio: This is a crucial stylistic choice rather than a pure performance metric. It is calculated by dividing the length of the diamond by its width.

The Bow-Tie Effect: Identifying and Avoiding This Common Flaw

A prevalent phenomenon in elongated fancy cuts Marquise, Oval, Pear, and Heart is the "bow-tie effect." This appears as a dark, bow-tie-shaped shadow stretching across the width of the diamond's center, obstructing its brilliance.

What causes it? The bow-tie is essentially a shadow caused by light leakage. It occurs when the pavilion facets are cut at angles that prevent light from reflecting back to the viewer. Instead, light falls into that area and is lost, creating a dark void. It is a direct result of poor cut proportions.

Is it always bad? A faint, transient bow-tie that is only visible from extreme angles can be found in even well-cut elongated stones. However, a prominent, dark bow-tie that is visible from multiple viewing angles and under various lighting conditions is a significant flaw. It detracts from the stone's beauty, brilliance, and ultimately, its value.

How to avoid it: The best defense is knowledge and scrutiny.

Prioritize Cut Quality: Choose a stone from a retailer, like CaratX, that provides a cut grade based on proven proportions.

Examine Videos and Images: When shopping online, insist on viewing high-definition videos of the exact diamond (not a stock video) from multiple angles. Reputable marketplaces will provide this.

View in Person: If possible, view the diamond in person under different light sources. Rotate it and observe how light moves within it.

The Art of Style: Choosing and Wearing Your Marquise Diamond

The Marquise cut is for the individual with a confident and refined sense of style. It is both classic and daring, making it incredibly versatile.

Flattering the Finger: The primary stylistic advantage of the Marquise is its ability to lengthen and slenderize the appearance of the finger. This makes it a perfect choice for those with shorter hands or fingers. If you have wider fingers or larger hands, you can balance your proportions by opting for a Marquise with a lower length-to-width ratio (closer to 1.75), which will emphasize its width over its length. Another stunning and modern option is to set the stone horizontally (East-West setting), which complements wider fingers beautifully.

Finding Your Ideal Ratio: While the classic ratio is 2:1, personal preference reigns supreme.

For a classic, traditional look: Aim for a ratio between 1.95 - 2.05. This is the most common and sought-after proportion.

For a fuller, more contemporary look: Choose a ratio between 1.75 - 1.85. This creates a stouter, more oval-like appearance.

For a dramatic, elongated look: Ratios above 2.10 will create a very sleek, slender effect.

Setting Styles to Consider:

The Timeless Solitaire: A simple solitaire setting in Platinum or 18K Yellow Gold allows the unique shape and brilliant sparkle of the Marquise to be the undeniable star of the show.

Beyond Diamonds: The Marquise Cut in Colored Gemstones

The beauty of the Marquise shape is not limited to diamonds. This cut is exceptionally popular in colored gemstones, where its elongated form can showcase the depth and saturation of a gem's colour magnificently. A deep blue sapphire, a rich ruby, or an emerald green Marquise cut gemstone makes for a profoundly unique and personal engagement ring or statement piece. Discover our expansive collection of natural gemstones to explore the possibilities.

Caring for Your Marquise Diamond

The pointed ends ("points") of a Marquise diamond can be vulnerable to chipping if struck hard. It is crucial to:

Choose a setting that protects the points, such as a V-prong or a bezel setting.

Remove your ring during physical activities, gardening, or cleaning.

Clean it regularly with a soft brush, mild soap, and warm water.

Have it professionally inspected and cleaned by a jeweler at least once a year to ensure the prongs are secure.
