The Basics

The oval diamond is a modified brilliant-cut. This is the perfect choice for customers who desire the appearance of a round diamond, but are looking for something more unique.

Another reason for the appeal of the oval cut diamond is its delicate, elongated shape, which creates the illusion of bigger size. The slim shape can make the finger of the wearer appear longer and slimmer.

Oval diamonds were one of our most popular cut of 2021.

Features

Oval cut diamonds of the same carat weight can appear vastly different due to their varied proportions. There is no GIA (Gemological Institute of America) grade for this cut due to its measurements, so it’s always a good idea to try out the stone in-store if possible.

A good oval cut is less prone to chipping, and the stone typically costs 10-20% less than a round diamond.

With ovals, a slightly thinner cut can look very enticing in a claw setting where the gem is flanked by side stones. If you have your eye on a particular diamond, we recommend that you ask for precise measurements, including length to width ratio, to find out the exact shape. You are looking for rounded ends, with no sharp edges or pointy tips.

"Oval cut diamonds often feature a degree of bowtie (an area of diminished sparkle or darkness), ranging from barely visible to severe. Importantly, you can’t accurately assess the extent of the bowtie effect by studying the diamond certificate or dimensions. A close visual inspection is necessary."

Historical Background

The oval cut was pioneered by Russian-born Lazare Kaplan in the 1960s. A veteran of the industry, Kaplan had begun his career in 1896 at the tender age of 13 — working at his uncle’s diamond cutting factory.

He was regarded as one of Antwerp’s most talented cleavers, especially noted for his skill in working severely cracked or flawed diamonds into smaller, beautiful stones.
