Anatomy of an Oval Diamond

Ovals are known as fancy shape diamonds. Fancy shapes will include all shapes except the round brilliant cut. These includes Cushions, emerald, princess marquise and radiant cuts, to name a few. Fancy shapes are also typically less expensive then round diamonds and makes them a popular choice when working on a budged or when you simply want to stand out!

When choosing an oval diamond its important to know the anatomy. Below you will find an illustration by GIA to help you understand the anatomy of the oval cut.

Typically, an oval diamond also has 57 or 58 facets like a round brilliant cut, giving it similar brilliance. Below

Other then most fancy shapes, ovals don’t have any sharp corners or angles, making it less likely to getting chipped or damaged when setting or even wearing it in a ring. Visually it also appears bigger than a round diamond of the same weight because of its bigger surface area, making it a great option for an engagement ring and is also gentler on the pocket.

History of the Oval Diamond

Around the 1700’s is when brilliant cut diamonds where introduced. Mostly cushion shapes at first as cutters tend to follow the natural outline of the rough crystals.

All of the shapes, including ovals where revered to as brilliant cuts back then. Only in the late 1800’s mention where made of oval diamonds in literature.

Late 1950’s showed the start of modern appeal for this shape with spike in popularity in the late 90’s and early 2000 partly driven by marketing campaigns.

Today oval diamonds are making a huge comeback and is a very popular alternative to round diamonds. According to Town & Country magazine, the oval diamond ranked 6th in popularity with American consumers in 2016 (round diamonds were still no. 1).

What to Look for in an Oval Diamond

As with any diamond, the 4Cs applies when looking to buy an oval diamond, the same as for a round brilliant cut diamond.

Length-to-Width Ratio

With oval diamonds, you need to keep in mind the proportions. This includes the Length to width proportions. Typically, they range from 1.3:1 to 1.4:1.

This 1.06 ct oval diamond has a 1.71:1 length-to-width ratio. It is rare to find oval diamonds this long. Photo: Kate Waterman/GIA

This 3.01 ct oval diamond has a 1.26:1 length-to-width ratio, which is a little shorter than most oval diamonds. Photo: Kate Waterman/GIA

This 2.28 ct oval diamond has a 1.48:1 length-to-width ratio. Even this length is a little hard to find. Photo: Kate Waterman/GIA

Symmetry

Equally important when cutting an oval diamond. When drawing and imaginary line down the centre of the diamond and again across, it needs to symmetrical and mirror each other.

Symmetry is based on how closely the shape and facets on either side of these imaginary centre lines mirror each other. Illustration: Peter Johnston/GIA

 

Shape Appeal

It’s best to look at a few options when shopping for an oval diamond the find the shape that appeals to you. Unlike round diamonds, ovals can come in various shapes depending on the cutter’ style and preference.

Bow-tie Effect

A commonly asked question, ‘’What is a bow tie in an oval diamond? ‘’

A ‘’bow tie’’ in a diamond is a dark bow shaped pattern, hence the name, across the middle of the diamond. You can expect to see this in Oval diamonds.

This is caused by reflections of your head and shoulders blocking the light from entering the diamonds when you are looking at it. This is because diamond facets act as mirrors that gather light around you and return it to your eyes. The closer you bring the diamond to your face the more obvious the effect will be. Having a well-cut diamond will minimise this effect.
