Elongated cushion cut diamonds have rounded corners, much like a cushion cut. The only difference is they have a longer, rectangular structure.

Technically, it's an elongated cushion cut when the length to the width ratio surpasses 1:1.1. 

How close the cut comes to a square or rectangular shape is a matter of choice, style, and personal taste. But usually, elongated cushion cuts are tall and skinny.

About the Elongated Cushion Cut Diamond

Elongated Cushion Cut Diamond

Cushion cut and elongated cushion cut diamonds are an updated version of the old mine cut from the 1700s. Also known as the candlelight cut, it’s considered a vintage style.

The old mine cut was used to cut diamonds from Brazil. After diamonds were discovered in South Africa, Brazil’s mines became known as the old mines. This is how the cut got its name.

The old mine cut had 58 facets. The modern cushion cut has 64 large, brilliant facets or more.

Elongated cushion cut diamonds display a high level of brilliance and fire. In fact, it is only slightly less brilliant than a round cut.
