Marquise Cut Diamonds — Regal Shape, Modern Spirit

With its elongated, pointed silhouette, the marquise cut diamond is one of the most distinctive and elegant shapes in the world of fine jewellery. Slender, symmetrical, and effortlessly dramatic, the marquise exudes both vintage glamour and contemporary edge.

Originally designed to emulate a royal smile, today the marquise cut makes its mark as a bold, style-forward choice — the perfect shape for someone who leads rather than follows.

What Is a Marquise Cut Diamond?

The marquise cut is an elongated shape with pointed ends and curved sides, sometimes referred to as a “navette” — meaning “little ship” in French, due to its boat-like outline. It typically features 56 facets, which create beautiful brilliance and elongation.

Its stretched form not only catches the light beautifully but can also appear larger than other cuts of the same carat weight. When worn in a north-south orientation, it lengthens the finger and brings a graceful, refined silhouette to the hand.

Who Is the Marquise Cut For?

The marquise cut is for those with confidence, charisma, and a deep appreciation for design. It suits wearers who favour originality and a sense of grandeur — often chosen by those who want their jewellery to stand out without being overstated.

It’s a shape that bridges eras — from 18th-century court opulence to modern minimalism — and makes a strong impression in both bold and delicate settings.

Signature Styles: How to Wear the Marquise

Sculptural and eye-catching, the marquise cut offers a wealth of design potential. Here are a few of our favourite ways to wear it:

Solitaires – Keep the focus on the shape itself with a clean, tapered band. The marquise speaks volumes on its own.

Halo Settings – A surrounding halo enhances brilliance and softens the angular points for a vintage-luxe effect.

East-West Orientation – Rotate the marquise horizontally for a modern, avant-garde twist on a classic cut.

Cluster or Multi-Stone Rings – Pair with rounds or pears for an asymmetrical, editorial look full of movement and personality.

Stackable Designs – Its length makes it ideal for slender, stackable bands that layer beautifully.
