Marquise cut
A long, narrow diamond pointed at both ends, also called the navette.
How to read it
GIA describes the marquise, also called the navette, as an elongated shape with two pointed ends; the International Gem Society calls it an elongated ellipse, which many compare to an eye or a football. GIA notes that the pointed tips can chip, which is why they are often set in V-shaped prongs.
