This is an elongated shape with tapering points at both ends. Its shape successfully flatters the finger, making it appear longer, so is a popular cut for gemstones in designer jewellery. It is important to consider the length-to-width ratio to maximize the beauty of this cut: usually a ratio of 2:1 is preferred, so that the length of the stone is about twice the width of the diamond. This works equally well in a simple solitaire setting or with side stones, particularly baguette or trillion shapes. A marquise-cut diamond is traditionally 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.
