Oval vs Round Engagement Rings: Which Is Right for You?

Choosing between an oval and round engagement ring usually comes down to two things: sparkle and size. Round diamonds are known for their exceptional brilliance, while ovals can look larger for their carat weight. Both are beautiful, popular choices, so it really comes down to the look you prefer.

This guide compares oval engagement rings and round engagement rings on size, price, sparkle and style.

Oval vs Round Diamonds at a Glance

An oval diamond can look larger and create the appearance of longer, slimmer fingers, while a round diamond is known for its exceptional light return. Round diamonds can also command a higher price per carat, while ovals often offer excellent value for their visible size.

Do Oval Diamonds Look Bigger Than Round Diamonds?

Oval diamonds can look bigger than round diamonds of the same carat weight. For example, a well proportioned 1 carat oval may measure around 7.7 mm x 5.7 mm, while a 1 carat round diamond is typically around 6.5 mm in diameter.

The difference is one of appearance, not weight. On a scale, the two stones are still the same carat weight. On the hand, the eye can read the oval's extra length as greater visible size, allowing it to cover more of the finger.

Are Oval Diamonds More Expensive Than Round?

Oval diamonds can offer excellent value compared with rounds of the same carat weight. Round diamonds are particularly popular and can command a higher price, while ovals can give you more visible size without necessarily increasing your budget as much.

Every Armans ring is made to order around the diamond you choose, so the best way to compare the two shapes is with a personalised quote. Our team can show you an oval and a round of the same carat weight side by side, making it easier to see how different proportions and cuts look in person.

If getting more size for your budget is important, lab grown diamonds are another option worth considering. Available in both oval and round cuts, they offer the same physical properties as mined diamonds and can give you more flexibility when it comes to size and design.

Which Sparkles More, Oval or Round?

If maximum sparkle is your priority, round is the clear winner. The round brilliant cut diamond has 57 or 58 facets arranged with exceptional symmetry, making it the benchmark for light return and brilliance. A well cut oval can also be incredibly bright, but it generally cannot quite match a round diamond of equal quality.

Ovals also have a feature that rounds do not: the bow tie. This is a darker band that can appear across the centre of an oval diamond. It can range from barely noticeable to quite prominent, depending on the diamond's cut and proportions. Our complete guide to oval cut diamonds explains what to look for when choosing an oval. 

Which Shape Suits Your Hand?

Both shapes suit most hands, but they create a different effect. An oval diamond runs along the finger and can create the appearance of longer, slimmer fingers. A round diamond is symmetrical and balanced, making it a classic choice for almost any hand shape.

Oval or Round: How to Decide

Choose an oval if you want a diamond that looks larger for its carat weight, creates a longer look on the finger, or gives you something a little less traditional. Choose a round if maximum sparkle and a classic, symmetrical look matter most.

There is no right or wrong choice between the two. The best shape is the one that suits your style, your hand and the way you want your engagement ring to look. Other diamond shapes may be worth considering too, and our diamond shape guide covers every option.

FAQs

Are oval engagement rings timeless?

Yes. Oval diamonds have been used in jewellery for decades, while oval gemstones have been popular for centuries. Although ovals have become particularly popular in recent years, the shape itself is well established and isn't simply a passing trend.

Is a round or oval diamond better for a solitaire?

Round and oval diamonds both make excellent solitaires. A round solitaire is a classic engagement ring choice and offers exceptional sparkle, while an oval solitaire can look larger and feel a little more distinctive.

A simple setting leaves nothing to distract from the centre stone, so the choice really comes down to the look you prefer.

Which is better for everyday wear, an oval or a round diamond?

Oval and round diamonds are both excellent choices for everyday wear when set securely. Neither shape has sharp points or corners, and both are durable enough for an engagement ring worn every day.

Your setting is also worth considering based on your lifestyle. A bezel setting or six-claw setting can offer extra protection for very active hands.

Do oval and round engagement rings suit the same wedding bands?

Oval and round engagement rings can both pair beautifully with straight, curved and diamond-set wedding bands. The fit depends more on how high the centre stone sits than on the diamond's shape.

Our team can match or custom make a band so the two rings sit beautifully together.

Can oval and round diamonds be combined in one ring?

Oval and round diamonds combine beautifully in one ring. A popular design is an oval centre stone with a round diamond on each side, or a band set with smaller round diamonds.

It is a lovely way to enjoy the distinctive look of an oval while adding the extra sparkle of round diamonds.

Can I see oval and round diamonds side by side before buying?

You can see oval and round diamonds side by side at the Armans showroom at 10/80 Castlereagh Street, Sydney. Comparing stones of the same carat weight in both shapes, on your own hand, can make the decision much easier.

These two shapes can be surprisingly difficult to compare on a screen, so seeing them side by side in person can make all the difference.
