The Marquise Cut Diamond Guide

By Devin Jones

Marquise Cut Diamonds

The marquise cut diamond is one of the most exotic diamonds featuring curved edges that meet at sharp points. The shape resembles an elongated American football or an abstract sketch of a human eye. Due to their unique design, marquise cut diamonds have by far the longest length to width ratio of any diamond shape, with an average length to 1.95, far exceeding the next longest length to width ratio (pear shape diamonds).

The elongated shape of a marquise cut diamond can make fingers appear slimmer and longer, but it doesn't make for a popular choice as an engagement ring diamond. Marquise cut diamonds are the 2nd least popular diamond shape ahead of only Asscher cut diamonds.

Brides who do opt for this shape are use to get a unique piece that draws attention. A marquise cut diamond is typically set north-to-south in an engagement ring setting with a prong covering both pointed ends to help protect them from accidental knocking. Notice how incredibly different the settings look with nearly the exact same diamond carat weight in the center.
