Marquise Cut

Marquise Cut is an elongated diamond shape with curved sides and pointed ends, creating a distinctive boat-shaped or eye-shaped outline. The shape is traditionally associated with the French court and is said to have been developed in the eighteenth century.

Marquise-shaped diamonds became increasingly popular in jewellery during the nineteenth and twentieth centuries. Their elongated outline can make a diamond appear larger than its weight might suggest and can create an elegant, elongated effect when set in a ring.

Marquise diamonds are generally cut using a brilliant-style facet arrangement, although the precise faceting and proportions can vary. The shape can produce strong brilliance and lively flashes of light when well proportioned.

One characteristic consideration with marquise diamonds is the pointed ends, which can be more vulnerable to damage. Antique examples may therefore have protective settings or surrounding designs that help shield the points.

Marquise Cut should not be confused with Navette. Both have an elongated, pointed appearance, but Navette primarily describes a jewellery shape or design, often associated with elongated rings and settings, whereas Marquise refers specifically to the characteristic pointed diamond outline and its cutting style.

Marquise diamonds can be particularly effective in antique and vintage jewellery, where their elongated form works well with floral, cluster and other decorative designs. They also became popular in twentieth-century engagement rings and dress jewellery.

At Weldons, marquise-cut diamonds are assessed not only for their size and brilliance but also for their proportions, symmetry, condition and how effectively the shape complements the individual jewel.
