Round and oval diamonds both exude an incredible amount because they’re both brilliant-cut stones. These two shapes have entirely rounded edges and offer impressive face-up dimensions compared to many other diamond shapes. They’re also two of the most popular diamond shapes for centre-stone engagement rings. 


While round and oval diamonds have a great deal in common, they also have some critical differences.


By examining the distinctions between these two attractive diamond shapes, you can narrow down your options and choose the just-right stone for your engagement ring.


Round Diamonds

What makes round diamonds the perennial best-selling shape?


Unmatched brilliance

Round diamonds are sometimes called “round brilliants,” and the name couldn’t be more fitting. Rounds exhibit fire, scintillation, and brilliance that other cuts simply can’t match. Most have 58 triangular or kite-shaped facets that radiate outward from the centre of the stone, casting light in every direction. 


For those who love sparkle, round diamonds are the only choice.


Classic appeal

Round diamonds appeal to those who prefer timeless, classic looks. And since women wear their engagement rings throughout their lives, they know a round diamond will withstand trends that come and go.


If you’re looking for a traditional engagement ring, consider a round diamond. Realise, however, that choosing the most popular shape comes with a heftier price tag.


Premium price tag

Because brilliant round diamonds are a favourite amongst consumers, you should expect to pay a premium. People are willing to pay more for items in high demand, and this is undoubtedly true for round diamonds. In fact, rounds can cost up to 25 per cent more than similar weight fancy shaped diamonds such as hearts, princess and radiant-cut diamonds.


Huge selection of settings

The popularity of round diamonds means jewellers have created a stunning variety of configurations that perfectly suit the shape. Whether you’re looking for platinum or rose gold, multiple stones or colourful gemstone accents, you’re likely to find what you’re looking for in a round diamond engagement ring.



Oval Diamonds

What’s causing the rise of the oval diamond?


Tradition with an elegant twist

If round diamonds offer a classic look, ovals provide unparalleled elegance. A perfectly proportioned oval diamond gives a nod to tradition while flaunting a unique, modern style of its own.


Maybe that’s why oval diamond sales have risen dramatically over the past three years. With celebrities like Hailey Baldwin, Scarlett Johansson and Blake Lively donning oval diamond engagement rings, it’s clear there’s a trend afoot.


Elongated styling

Some people prefer oval diamonds over rounds because they make fingers appear longer and more slender. Women with long, thin fingers appreciate the way oval diamonds accent their natural features. Likewise, women with shorter fingers love the illusion of length created by the diamond’s shape.


Advantageous proportions

Carat for carat, oval diamonds appear more substantial than rounds. Therefore, an oval diamond will give you more bang for your buck. If a large diamond is essential to you, consider choosing an oval over a round.


Most people prefer a length-width ratio of 1.3:1 to 1.5:1 for oval diamonds. This range creates the most balanced, desirable shapes. Remember, however, that personal preference should dictate the shape of the diamond. 



Questions to Ask Yourself

If you’re still struggling to choose between round and oval diamonds, ask yourself the following questions.

  • Do I prefer traditional or modern styling? (Round is traditional, oval is modern)
  • Am I seeking the largest possible diamond for my budget? (Oval)
  • Do I want a timeless diamond that will remain a classic? (Round)
  • Do I want to choose an on-trend diamond? (Oval)
  • Are you engagement ring shopping on a budget? (Oval)
  • Do you want to be able to select from a vast array of settings? (Round)
