What Is a Dutch Marquise Diamond?

The Dutch Marquise — also known as the Hexagonal Marquise — is a rare and modern diamond cut that marries the bold geometric lines of a hexagon with the elongated silhouette of the classic marquise. The result is a shape that is unmistakably distinctive: six clean edges tapering to two pointed ends, with a crown structure that maximises brilliance.

Unlike traditional marquise cuts, the Dutch Marquise introduces flat, angular sides that give it a graphic, architectural quality. It appeals to the modern bride seeking something truly one-of-a-kind — a diamond that turns heads and tells a story.

The Geometry of Brilliance

Every Dutch Marquise is defined by its elongated hexagonal outline. The top and bottom come to sharp points like a traditional marquise, while the four lateral sides are flat and straight — creating a shape reminiscent of a cut emerald yet with the sparkle of a brilliant cut.

• Elongating effect — the shape makes fingers appear longer and more slender when set in a ring.
• Finger coverage — the broad face of the stone gives excellent visual size per carat weight.
• Brilliant-cut faceting — despite its geometric outline, internal facets deliver high fire and sparkle.
• Bowtie minimisation — with skilled cutting, the classic marquise bowtie effect is dramatically reduced.
• Versatile orientation — can be set vertically, horizontally, or on a diagonal for creative designs.

How to Choose Your Dutch Marquise Diamond

• Color: Because the Dutch Marquise has a large open face, opt for D–G color grades to avoid visible warmth in the stone's body.
• Clarity: VS1–VS2 is ideal — inclusions near the tips are more visible due to the pointed ends, so tip clarity matters.
• Cut quality: Look for excellent or ideal cut grades. A well-cut Dutch Marquise will show minimal bowtie and maximum brilliance.
• Setting: V-prong settings protect the pointed ends while remaining virtually invisible — the preferred choice for Dutch Marquise rings.
• Ratio: A length-to-width ratio between 1.75:1 and 2.15:1 is considered most pleasing for the Dutch Marquise shape.
