Oval Cut Diamonds

If you love the curved edges and sparkle of a round diamond, but want something more unique, an oval diamond fits the bill. It’s often said that oval cut diamonds are somewhere between the round and the Marquise shape.

 

What is an oval shape diamond?

The basics

As their name suggests, oval diamonds are symmetrical, elongated rounded shapes which possess a similar level of fire and brilliance to that of a round diamond. They are a modified brilliant cut, which means they share the same faceting pattern as round brilliant diamonds. The oval cut combines the timeless elegance of a round diamond with the elongated silhouette, creating a unique and versatile shape.

Oval cut diamonds typically have 58 facets, including a large flat table on top and a pointed culet at the bottom. The curved sides of the diamond give it an elongated appearance, with rounded ends that can vary in their degree of elongation. The length-to-width ratio of oval cut diamonds can vary, allowing for customization based on personal preference.

Why should I choose an oval diamond?

With an increased surface area, an oval diamond optimises carat weight; this means that oval diamonds often appear larger than a round diamond of the same carat weight–an impressive and economical choice.

The elongated shape is also known to flatter the wearer as they move with the natural lines and curves of your finger. It has the ability to create the illusion of longer, slender fingers when worn as an engagement ring. The elongated shape offers a flattering and elegant look on the hand.

Oval cut diamonds exhibit excellent brilliance and sparkle. When well-cut, they can showcase a beautiful play of light, with impressive fire and scintillation. The oval shape disperses light in a radiant manner, giving the diamond a lively and eye-catching appearance.

Oval diamonds make up around 15% of our engagement ring sales, making them the second most popular shape after round.

Who’s wearing oval diamond engagement rings?

In recent years, oval diamond engagement rings have seen an increase in popularity, with stars like Hailey Baldwin and Blake Lively leading the trend.

What ratio oval should I choose?

Oval diamonds are available in ratios (length divided by width) from 1.30 to 1.60, with the most popular between 1.30 to 1.45.

What’s your ideal ratio? It’s a matter of personal preference–a larger ratio will give a narrow, long oval shape, elongating the wearer’s finger, while a smaller ratio will give a more rounded shape, often more likely to prevent a bow tie effect.

What factors should I consider when choosing a oval diamond?

Avoid a bow-tie effect

Oval diamonds can possess a bow-tie effect, which occurs when the light doesn’t bounce into the middle of the diamond, because of the way the diamond is cut.

This appears as a bow-tie shape darkness visible in the centre of the diamond. While most agree that this a part of an oval diamond’s beauty, a severe effect, as shown, is undesirable.

All of our diamonds are hand-inspected by our diamond buyer to ensure they do not possess a strongly visible bow-tie.

Oval Diamond Cut Colour

Choosing colour grade in oval cut diamonds is entirely dependent on the preference of its buyer or wearer.

Some customers prefer the warmer tones of colour grades G-H to the icy cool tones of colour grades D-F.

In fact, if you’re choosing a rose gold or yellow gold setting, choosing a diamond with a colour range G-J is a great choice. The warm tones from the metal will mask any minor colour present in the diamond.

In reality, the difference between these two colour grade ranges (colourless and near colourless) is difficult to perceive, especially to the naked eye.

Oval Clarity

What clarity is best for an oval cut diamond?

Clarity really is dependent on personal preference. When diamonds are formed deep in the earth, they develop clarity characteristics–slight irregularities visible under 10x magnification. Depending on the size, quantity, placement, tone or colour of these clarity characteristics, they may or may not be visible to the naked eye. This is one of the reasons why a truly flawless diamond is so rare.

Some people may be entirely comfortable with a diamond that features clarity characteristics (also known as inclusions) that aren’t visible to the naked eye. Others may insist on a technically flawless appearance for absolute perfection.

To ensure the brilliance and fire that makes oval diamonds so enchanting, we recommend SI1 clarity grades or higher.
