A marquise ring symbolizes elegance, sophistication, and romance. The marquise shape diamond was originally designed to resemble the lips of the Marquise de Pompadour, the mistress of King Louis XV of France. The shape is also associated with a hereditary rank above a count but below a duke, and with a small ship, due to its boat-like form. A marquise ring is a popular choice for engagement rings, as it is believed to represent a union of two souls. The marquise shape diamond also has the advantage of making the finger appear longer and more slender.
