Marquise

The marquise cut is a regal, elongated shape with tapering points at both ends. Its shape tends to flatter the finger, making it appear longer.

When choosing a marquise cut, the length-to-width ratio should be considered. Usually a ratio of 2:1.0 is preferred, meaning that the length of the stone should be about 2 times the width of the diamond.

However, like all fancy shapes, personal preference prevails, and some may prefer a shorter, wider outline or longer, thinner shape. Just look for good symmetry to ensure overall beauty no matter what outline you prefer.

This shape works in a simple solitaire setting or looks beautiful with side stones, especially baguette or trillion shapes.

A marquise-cut diamond should be mounted with six prongs: four positioned on the sides to hold the body of the stone securely and two V-shaped prongs to protect the points at either end, the most vulnerable part of the diamond.
