Marquise shape, английский
The marquise cut is an elongated shape with tapering points at both ends. its shape allows the cutter to maximize carat weight, giving the appearance of a larger-looking diamond and tends to flatter the finger, making it appear longer. the most traditional marquise-cut diamonds, have a length-to-width ratios between 1.75 and 2.25.
