Engagement Rings
Marquise Cut engagement rings.
The marquise cut diamond engagement ring is a regal and dramatic choice with a fascinating history. Named after the Marquise de Pompadour, this boat-shaped diamond was commissioned by King Louis XV of France to resemble the perfect smile of his beloved. With its elongated body and two pointed ends, the marquise cut maximises carat weight appearance — it has one of the largest face-up surface areas of any diamond shape, making it look significantly bigger than its actual carat weight. Its elegant profile elongates the finger beautifully. Explore our GIA and IGI certified marquise collection, or visit our showrooms for a free consultation.
Buying Guide
Everything you need to know about marquise cut diamond engagement rings.
The marquise is a modified brilliant cut with 58 facets, offering impressive brilliance and fire in a truly distinctive silhouette. When selecting a marquise diamond, the ideal length-to-width ratio falls between 1.75 and 2.25, with 2.00 being the most classic proportion. Symmetry is paramount — the two pointed ends must align perfectly, and the curved sides should mirror each other exactly. Like ovals and pears, marquise diamonds can display a bow-tie effect, so each stone should be assessed for balanced light performance. Protective V-prong settings are essential for the two pointed tips to prevent chipping.
What is the history behind the marquise cut diamond?
The marquise cut originated in 18th-century France when King Louis XV commissioned a diamond to be cut in the shape of the Marquise de Pompadour's smile. This romantic French origin gives the shape its name and its regal association. Over the centuries, it has evolved into a modified brilliant cut that combines historical charm with modern light performance.
Do marquise cut diamonds show a bow-tie effect?
Yes, like ovals and pear shapes, marquise diamonds can exhibit a bow-tie — a dark shadow across the centre of the stone caused by light leakage. A faint bow-tie is normal and can add depth, but a prominent one diminishes the diamond's beauty. Every marquise in our collection has been inspected to ensure minimal bow-tie and maximum brilliance.
What is the ideal length-to-width ratio for a marquise diamond?
The most popular length-to-width ratio for a marquise diamond is around 2.00, which creates a classic, balanced boat shape. Ratios between 1.75 and 2.25 are generally considered ideal, with narrower ratios appearing wider and more rounded, and higher ratios looking more slender and elongated. We recommend viewing different ratios at our showrooms to find your preference.
How should the pointed tips of a marquise diamond be protected?
The two pointed ends of a marquise diamond are the most vulnerable to chipping, so V-prong settings are essential to shield them. These prongs cover and reinforce the tips while allowing maximum light to enter the stone. For extra security, a bezel setting wraps the entire perimeter of the diamond, offering the highest level of protection.
Does a marquise diamond look larger than other shapes of the same carat weight?
Yes, the marquise cut has one of the largest face-up surface areas of any diamond shape, meaning it appears significantly larger than a round or cushion diamond of the same carat weight. This makes it an excellent choice for those who want maximum visual impact. Its elongated form also creates the illusion of longer, more slender fingers.
