The Marquise cut diamond, a gem of royal lineage and breathtaking elegance, is celebrated for its distinctive boat-shaped silhouette, with pointed ends and a gracefully curved center. Originating in the 18th century, inspired by the smile of the Marquise de Pompadour as commissioned by King Louis XV of France, this brilliant cut features 56 to 58 facets designed to maximize light reflection. Its elongated shape and radiant sparkle create a dramatic, eye-catching effect, making it a favorite for engagement rings, pendants, and statement earrings. At Icestore, our GIA-certified Marquise cut diamonds capture this historic allure, offering clients the opportunity to craft jewelry that blends timeless sophistication with modern brilliance, backed by innovative technology and unparalleled craftsmanship.

 

Why Choose a Marquise Cut Diamond?

​

Striking Elegance and Elongation

The Marquise cut’s slender, elongated shape creates a flattering effect, visually lengthening the finger when set in rings or adding a graceful drop to pendants and earrings. Its brilliant faceting delivers a vibrant interplay of light, producing a dazzling sparkle that rivals the round brilliant while offering a unique, aristocratic profile. This cut’s regal aesthetic appeals to those seeking a diamond that combines bold presence with refined beauty, perfect for making a memorable statement.

​

Versatile Design Potential

With its ideal length-to-width ratio of 1.75–2.25, the Marquise cut adapts effortlessly to a variety of jewelry styles, from vintage-inspired solitaires to modern multi-stone or halo settings. Its pointed ends and curved sides make it a striking centerpiece, complementing accent stones, colored metals, or intricate designs. Whether oriented horizontally or vertically, the Marquise cut’s versatility allows for creative customization, ensuring a piece that reflects individual style and personality.

​

Enhanced Visual Impact

The Marquise cut’s elongated shape gives the illusion of a larger carat size compared to other cuts of the same weight, offering exceptional value for those seeking a bold look. Its brilliant facets help mask minor inclusions, making a clarity grade of VS2 or higher ideal for an eye-clean appearance, while its ability to enhance color makes it suitable for near-colorless grades (G–I). This combination allows buyers to prioritize size or design while maintaining a stunning, high-quality gem.

For Marquise cuts, Icestore recommends a clarity of VS2 or higher and a color grade of I or better to achieve a flawless, vibrant look, with meticulous attention to symmetry to ensure balanced proportions between the pointed ends. Our GIA-certified diamonds are handpicked for exceptional polish and light performance, delivering gems that radiate brilliance.
