An eye-shaped gemstone, known as the Marquise cut, is not a new stone shape. In fact, it is thought to owe its delightful silhouette to Madame de Pompadour, the mistress of 18th century French King Louis XV. It is alleged that he commissioned this diamond cut to resemble his mistress’ beautifully shaped mouth.
For most of its long history, the Marquise cut gemstone has been placed in jewelry in a vertical orientation. Set in a ring, the Marquise cut with its slender shape and gracefully pointed tips at both ends tends to elongate a lady’s finger, creating an elegant look.
