The regal navette.
The marquise diamond is the most carat-efficient shape in existence — its elongated, boat-shaped outline covers more surface area per carat than any other cut. Legend traces its origin to 18th-century France, where King Louis XV commissioned a diamond to mirror the lips of his mistress, the Marquise de Pompadour.
Every oval diamond in our collection is GIA, HRD or IGI certified and individually selected for balanced symmetry and minimal bow-tie. Its dramatic pointed ends and curved body create a striking, regal silhouette that elongates the finger like no other shape.

What makes it special
Key Characteristics
Why the marquise delivers the most dramatic visual impact of any diamond shape.
Largest Face-Up Size
The marquise has the biggest face-up surface area per carat of any diamond shape. A 1-carat marquise looks significantly larger than a 1-carat round — giving you maximum visual impact for your budget.
Royal Heritage
Commissioned by King Louis XV of France around 1745, the marquise carries aristocratic DNA. Its French name means "nobleman's wife" — and its regal silhouette still commands attention centuries later.
Dramatic Elongation
The pointed ends and narrow body create the most dramatic finger-lengthening effect alongside the pear. The marquise makes even shorter fingers appear long and slender.
Brilliant Sparkle
As a modified brilliant cut with 56 facets, the marquise delivers intense brilliance and fire. Its elongated shape also creates unique light patterns as it moves — catching the eye from across the room.

Expert Advice
Why Choose a Marquise Diamond?
The Biggest-Looking Diamond Per Carat
No other shape gives you as much visible surface area per carat weight. A well-proportioned marquise can appear up to 15% larger than a round of the same carat — making it the smartest choice for maximum visual impact on a budget.
Striking & Unique Silhouette
In a world dominated by rounds and ovals, the marquise stands apart. Its boat-shaped outline (also called "navette") is instantly recognisable and projects confidence and individuality — without being unconventional.
Exceptional Value
Marquise diamonds typically cost 30–40% less than a comparable round brilliant. Lower demand and excellent rough utilisation mean you get both a larger-looking stone and a higher quality grade within the same budget.
Creative Setting Options
Wear it north-south for classic elongation, or east-west for a bold, modern statement. The marquise also pairs beautifully with tapered baguette side stones and three-stone arrangements — offering more creative versatility than most shapes.
A Story Worth Telling
Few diamonds come with a story as romantic as the marquise — commissioned by a French king to capture the smile of his beloved. This aristocratic heritage adds meaning beyond the stone's physical beauty.
