Marquise Cut

Marquise cut diamonds are boat-shaped, and are a very popular choice for an engagement ring. A marquise cut diamond undergoes a similar cutting process to that of a round diamond, but the carat weight of the marquise diamond is maximized by elongating it into its easily recognizable shape.
