This distinctive cut, known for its elongated shape and pointed ends, has evolved from its noble origins to become a sophisticated choice in modern jewelry. Understanding its characteristics, benefits, and specific requirements helps in making an informed decision when considering this elegant diamond cut.

Marquise Cut Diamond Basics

The Marquise cut diamond represents a masterpiece of diamond cutting expertise, combining complex angles and proportions to create maximum brilliance. This boat-shaped brilliant cut demonstrates how precise cutting techniques can transform rough diamonds into spectacular gemstones that appear larger than their actual carat weight while maintaining exceptional fire and brilliance.

• The Marquise cut features 58 precisely arranged facets, with 33 facets on the crown and 25 on the pavilion, creating an intricate pattern that maximizes light return and creates the distinctive sparkle associated with high-quality diamonds. These facets must be cut with perfect symmetry to achieve optimal brilliance and minimize the bow-tie effect that can appear in the center of the stone.
• The ideal length-to-width ratio for a Marquise cut typically falls between 1.75 and 2.25, with 2.0 considered the perfect balance by most gemologists. This ratio significantly impacts the diamond’s appearance and should be chosen based on personal preference and intended jewelry setting. Ratios outside this range may appear either too narrow or too wide, potentially affecting the stone’s visual appeal.
• The cut’s proportions play a crucial role in its performance, with ideal parameters including a table percentage between 53-63% and a depth percentage between 58-62%. These specifications ensure optimal light reflection and refraction, creating the maximum brilliance and fire that make diamonds so captivating.
• Marquise cuts typically display a bow-tie effect – a dark area crossing the center of the stone caused by light blockage. While this effect is present in all Marquise cuts, its visibility varies significantly based on cutting quality. A well-cut stone minimizes this effect while maintaining optimal brilliance.
• The pointed ends of a Marquise cut require special consideration in setting and wear. These points are more vulnerable to damage and should be protected by appropriate setting techniques, such as V-prong or bezel settings. The setting should also ensure the points are perfectly aligned for optimal symmetrical appearance.
• Color retention in Marquise cuts tends to be stronger at the points, making color grade selection particularly important. Experts often recommend choosing a higher color grade than you might for other cuts to ensure a consistent appearance across the entire stone.

Beyond their technical specifications, Marquise cut diamonds offer practical advantages that have maintained their popularity through generations. Their elongated shape creates an illusion of greater size, making them an excellent choice for those seeking maximum visual impact from their diamond selection while maintaining the sophistication of a classic cut.

The Royal Origins of Marquise Diamonds

The Marquise cut’s history intertwines with French royalty and romantic gestures, making it one of the most historically significant diamond cuts. This shape’s evolution from a royal commission to a modern brilliant cut demonstrates how diamond cutting techniques have advanced while maintaining the cut’s distinctive character and elegant appeal.

• The Marquise cut originated in 18th century France during the reign of King Louis XV (1710-1774). The king commissioned a diamond cut to mimic the shape of his mistress’s lips – Jean Antoinette Poisson, the Marquise de Pompadour. This romantic gesture gave birth to the “navette” cut, meaning “little boat” in French, which later became known as the Marquise cut.
• The original cutting technique used in the 18th century was significantly different from modern methods. Early Marquise cuts featured fewer facets and less precise proportions, resulting in lower brilliance compared to today’s cuts. The evolution of cutting technology and understanding of light performance has transformed the original design into the brilliant cut we see today.
• During the Victorian era (1837-1901), the Marquise cut gained popularity among European nobility, who appreciated its unique shape and romantic history. This period saw the cut being used not only in rings but also in elaborate brooches and pendants, establishing its versatility in various jewelry designs.
• The modern Marquise brilliant cut emerged in the 1960s, when advanced cutting techniques and mathematical precision enabled cutters to maximize the stone’s light performance. This development period established the current standard of 58 facets and precise proportional guidelines.
• The name “Marquise” itself reflects the stone’s noble heritage. In French aristocratic hierarchy, a Marquise ranked below a duchess but above a countess, signifying the cut’s prestigious status in jewelry history. This association with nobility has contributed to its enduring appeal in fine jewelry.
• Throughout the 20th century, the Marquise cut has experienced several peaks in popularity, notably during the 1960s and 1980s, demonstrating its ability to adapt to changing fashion trends while maintaining its classic appeal.

The Marquise cut’s journey from a royal commission to a standardized brilliant cut reflects broader developments in diamond cutting technology and changing aesthetic preferences.

Understanding Marquise Diamond Shape

The Marquise cut’s distinctive physical characteristics make it unique among diamond cuts. Understanding these features is crucial for both appreciating the cut’s beauty and making informed decisions when selecting a stone. The precise arrangement of facets and proportions determines not only the diamond’s appearance but also its brilliance and overall performance.

• The standard Marquise cut consists of 58 facets arranged in a specific pattern to maximize brilliance and fire. Each facet plays a crucial role in light performance, with the crown facets primarily handling light dispersion (creating fire) and the pavilion facets managing light reflection (creating brilliance). The precise alignment of these facets is critical for optimal light return.
• The typical length-to-width ratio ranges from 1.75 to 2.25, though stones can be cut outside these parameters. This ratio significantly affects the stone’s appearance and perceived size. At 1.75, the stone appears more compact and rounded, while at 2.25, it appears more elongated and slender. The choice of ratio often depends on personal preference and intended use.
• The bow-tie effect, a visual phenomenon appearing as a dark area across the center of the stone, is inherent in Marquise cuts due to their elongated shape. While this effect cannot be completely eliminated, its visibility varies significantly based on cutting quality. Expert cutters minimize this effect through precise facet placement and angle calculations.
• Critical measurements in a Marquise cut include table percentage (53-63% ideal), depth percentage (58-62% ideal), and girdle thickness (thin to slightly thick). These proportions work together to create optimal light performance while maintaining structural integrity. Deviations from these ideals can affect both brilliance and durability.
• Symmetry is particularly crucial in Marquise cuts, more so than in many other shapes. The points must align perfectly, and the two halves of the stone should mirror each other exactly. Even slight asymmetry can be visible to the naked eye and significantly impact the stone’s beauty and value.
• The pointed ends, while distinctive, require specific cutting techniques to ensure durability. These points should be equal in length and precisely aligned with the diamond’s long axis. The angles at these points significantly affect both the stone’s durability and its ability to be securely set.

The physical characteristics of a Marquise cut diamond represent a careful balance between aesthetic appeal and practical considerations. Understanding these elements helps in appreciating the complexity of this cut and ensures informed decisions when selecting or caring for a Marquise cut diamond.

How to Choose a Marquise Cut Diamond

Selecting the perfect Marquise cut diamond requires attention to several key factors that affect both its beauty and value. This process involves understanding specific quality parameters unique to the Marquise shape, beyond the standard 4Cs of diamond grading. A systematic approach to evaluation ensures you select a stone that offers both visual appeal and lasting quality.

• Cut quality in Marquise diamonds requires special attention to symmetry and proportions. The stone’s two halves must mirror each other perfectly, with points precisely aligned along the central axis. The shoulders (curved areas near the points) should be symmetrical, and the belly (widest part) should be exactly centered. Even slight asymmetry can significantly impact the stone’s beauty and value.
• When evaluating clarity in Marquise cuts, pay particular attention to inclusions near the points and center. While the brilliant faceting pattern can help mask some inclusions, those near vulnerable areas like points can affect durability. VS2 to SI1 clarity grades often provide the best value, as inclusions are typically not visible to the naked eye at these grades while keeping costs lower than higher clarity grades.
• Color grades in Marquise cuts require careful consideration due to color concentration at the points. Consider selecting a color grade at least one grade higher than you might for a round brilliant, particularly if setting in white metals. For stones over 1 carat, H color or better is recommended for a colorless appearance, while I-J colors can offer value in yellow gold settings.
• Length-to-width ratio selection should balance personal preference with practical considerations. While ratios between 1.75 and 2.25 are traditional, consider how different ratios might complement hand size and intended setting style. Longer ratios create a more dramatic appearance but may require more protective settings.
• The bow-tie effect requires in-person or detailed video evaluation, as it’s not included in grading reports. A well-cut Marquise should show minimal to moderate bow-tie effect, which can actually add character to the stone. However, severe bow-ties that appear as dark, distinct patterns across the center should be avoided.
• Setting selection significantly impacts both the stone’s appearance and security. V-prong settings offer essential protection for the points while maintaining maximum light entry. Consider how different setting heights and styles might affect daily wear and maintenance requirements.

Choosing a Marquise cut diamond involves balancing these various factors against personal preferences and practical considerations. Understanding these elements helps ensure selection of a stone that will provide both immediate beauty and long-term satisfaction.

Each point should be secured by a V-shaped prong that cradles the tip while allowing maximum light entry. The setting typically uses 4 or 6 prongs total, with V-prongs at the points and traditional prongs along the sides.
• Bezel settings offer maximum protection for Marquise cuts by completely encasing the stone’s edges in metal. While this style sacrifices some light entry, it provides superior protection for active lifestyles. Modern bezel designs can incorporate partial bezels or creative metalwork to maintain brilliance while protecting vulnerable areas. This setting style is particularly suitable for everyday wear jewelry.
• Halo settings have gained popularity for Marquise cuts as they enhance the stone’s perceived size and add additional sparkle. The surrounding small diamonds can be set to follow the Marquise shape exactly or create new outlines, such as oval or elongated cushion shapes. This versatility allows for unique designs while maintaining secure stone setting.
• East-west settings (horizontal orientation) represent a modern alternative to traditional vertical placement. This orientation creates a unique look while potentially offering better protection against impact in ring designs. The horizontal placement can make rings more comfortable for daily wear and provides a contemporary twist on classic designs.
• Channel and pavé settings for side stones complement the Marquise’s elongated shape particularly well. These settings can create elegant tapered designs that enhance the center stone’s length while adding overall brilliance. The gradual diminishing size of side stones can create a harmonious flow that complements the Marquise cut’s natural lines.
• Three-stone settings featuring a Marquise center stone offer opportunities for creative stone combinations. Complementary side stones can be used to either enhance the elongated look (using tapered baguettes or smaller Marquise cuts) or create contrast (using round or princess cuts). The key is maintaining proportion and balance in the overall design.

The setting choice for a Marquise cut diamond significantly impacts both its appearance and longevity. Careful consideration of lifestyle requirements alongside aesthetic preferences ensures a setting that provides both beauty and practicality.
