The marquise diamonds are a modified brilliant-cut in the shape of a football. The name comes from the Marquise of Pompadour, for whom King Louis XIV of France purportedly had a stone forged to resemble what he considered her perfectly shaped mouth.
Marquise diamonds can also create the illusion of greater size due to their narrow and long shape. Carat for carat, this diamond has one of the greatest crown surface areas of any diamond shape, making it an excellent choice when trying to maximize the perceived size of a diamond. Similar to the oval diamond, the marquise cut diamond's elongated shape can also make the wearer’s finger appear slimmer and longer.
