Marquise Cut Diamonds & Gemstones

Inspired by the smile of the Marquise de Pompadour


Marquise cut diamonds and gemstones make for very elegant engagement rings as they tend to be flattering to the hand, making fingers look longer and more slender. Despite this, marquise cut engagement rings remain quite unusual, so if you think she'd prefer something a little different, this could be a great choice.

Marquise diamond plot Marquise cut diamonds, also known as navette cuts (French for "little boat") are a modified brilliant cut with 58 factets. The cut was allegedly inspired by the striking smile of the Marquise de Pompadour, King Louis XV’s mistress. Compared to many shapes, a marquise will tend to have a larger crown area relative to its weight, which means that at any given weight the marquise will tend to seem larger - this can be helpful, if you want to maximise your diamond's perceived size within a given budget.

A marquise cut is considered to have ideal proportions when the the length of the diamond is approximately twice its width, though more slender or wider proportions may suit a particular design. Whichever proportions you prefer, you should always look for very good or excellent symmetry and polish, as this ensures that light is reflected evenly, especially in the point.

As there isn't a universally recognised ideal shape for a marquise, a GIA certificate won't list a 'Cut' grade. However, it's worth checking that a stone has a Table % between 52 and 65, and a Depth % between 56 and 66. Numbers outside these ranges are likely to signify a badly cut diamond.
