When choosing a diamond engagement ring, shape is more than just an aesthetic decision – it affects how big the diamond looks on your finger.

Round and square-shaped diamonds are both popular, but each offers a unique visual impact that can influence the perceived size.

This guide explores whether square or round diamonds tend to appear larger on the finger, considering factors such as shape, setting, and overall design.

Understanding Diamond Shapes: Square vs. Round

Before we dive into which shape looks bigger, let’s take a closer look at the characteristics of square and round diamonds.

Each shape has distinctive features that can affect the diamond's apparent size and how it complements different fingers.

Square Diamonds

Square-shaped diamonds come in various cuts, such as princess, cushion, radiant, and Asscher.

If you're interested in finding the perfect square shape, you can check out our princess lab-grown diamond collection, which features sharp edges for a modern look.

For those who prefer softer edges, the cushion-cut diamonds are a popular choice.

Round Diamonds

The round brilliant cut is by far the most popular diamond shape, known for its timeless appeal and unmatched brilliance.

To explore different options, you can search for round lab-grown diamonds and find the perfect stone to match your style.

However, round diamonds can sometimes appear smaller than square diamonds of the same carat weight because they tend to be cut deeper, which affects how much of the diamond's weight is visible from above.

How Diamond Shape Affects Perceived Size

Several factors determine how large a diamond appears, and shape plays a significant role.

Two key considerations are the face-up area – the visible surface of the diamond – and how the stone is cut.

Face-Up Area and Spread

The face-up area refers to the surface space visible from the top view.

Diamonds with a larger face-up area generally appear bigger.

Square diamonds usually have a wider face-up area compared to round diamonds of the same carat weight, which can make them seem larger on the finger.

However, this isn’t the only factor in play.

Cut and Proportions

The quality of the diamond’s cut affects not just its brilliance but also how large it appears.

If you're considering different cuts, the radiant-cut diamonds offer a balance between the square shape and brilliant sparkle.

In contrast, some square cuts, like the princess cut, may have less depth, allowing more of the diamond’s carat weight to be seen from above.

Do Square Diamonds Appear Larger on the Finger?

Square diamonds often create the illusion of a larger size due to their angular shape and increased face-up area.

Here’s why they might appear more substantial:

Wider Face-Up Area

Square-shaped diamonds, particularly the princess cut, tend to have a wider face-up area than round diamonds of the same carat weight.

This means more of the diamond’s surface is visible when viewed from above, making the stone appear larger.

Sharper Edges Enhance Size Perception

The sharp edges of square diamonds create a defined outline that can catch the eye, giving the impression of a bigger diamond.

This effect can be particularly noticeable on longer fingers, where the angular shape enhances the diamond’s presence.

If you like the look of sharp edges, Asscher-cut diamonds may also be a good choice for a more vintage-inspired appearance.

Ideal for Certain Finger Shapes

Square diamonds can be especially flattering on longer fingers, where their geometric form adds elegance without elongating the finger further.

They can also suit those who prefer a more contemporary look for their engagement ring.

Do Round Diamonds Appear Larger on the Finger?

Round diamonds may not have the widest face-up area, but they have other qualities that can make them appear substantial.

Brilliance and Light Reflection

Round brilliant-cut diamonds are renowned for their exceptional sparkle, which can create the illusion of a larger size.

The way a round diamond catches and reflects light can make it stand out more, especially when viewed in well-lit environments.

Compatibility with Various Ring Settings

Round diamonds work well with a wide range of settings, which can further enhance their size appearance.

For instance, a halo setting, where smaller diamonds surround the central stone, can make a round diamond look significantly larger.

Bezel settings, which encircle the diamond in a metal frame, can also give the impression of an expanded surface area.

Suitability for Different Finger Types

Round diamonds are versatile and can suit almost any finger shape.

On shorter or wider fingers, the round shape can create a balanced appearance, making the finger look slimmer while still giving the diamond a prominent presence.

Other Factors Influencing Diamond Appearance

While shape plays a crucial role, other elements can influence how large a diamond looks on the finger.

These include the ring setting, finger shape, and even diamond quality.

Ring Setting and Style

The setting is a powerful tool for enhancing a diamond’s size appearance.

A halo setting can add extra sparkle and make the centre stone appear larger, while a simple solitaire setting allows the diamond to stand out without distractions.

Side-stone settings can also draw attention to the centre diamond, enhancing its visual impact.

For a touch of colour, fancy coloured diamonds can add a unique sparkle, which may also impact the diamond's perceived size.

Finger Size and Shape

Finger size and shape can influence how big or small a diamond appears.

A larger diamond may be needed for a wide finger to achieve a similar visual impact to a smaller diamond on a slender finger.

Additionally, some shapes, such as square cuts, may look more prominent on longer fingers, while round diamonds can create a balanced look on shorter or wider fingers.

Diamond Colour and Clarity

A higher colour grade can make a diamond appear more brilliant, enhancing its perceived size.

Similarly, a diamond with excellent clarity will sparkle more, drawing attention to its size.

While these factors don’t change the actual dimensions of the diamond, they can influence its visual appeal.

Tips for Choosing the Right Diamond Shape Based on Appearance

When it comes to picking a diamond shape, considering your finger shape, setting, and budget can help you find the perfect ring.

Consider Finger Shape and Size

For longer fingers, square diamonds can create a stylish, modern look, while round diamonds may provide a softer appearance.

Those with shorter or wider fingers might find that round diamonds help create a balanced look.

Choose the Right Setting

Selecting the right setting can significantly impact how large your diamond appears.

If you’re aiming to make the diamond look bigger, opt for settings like halo, bezel, or side-stone styles that add extra visual appeal.

Maximise Perceived Size on a Budget

If you’re working with a budget, there are ways to make a smaller diamond appear larger without increasing the carat weight.

Choosing a halo setting, which adds a ring of smaller diamonds around the centre stone, can create the illusion of a bigger diamond.

Alternatively, opting for a shallower cut with a wider table can enhance the face-up area.

FAQs

Does the carat weight influence the perceived size difference between square and round diamonds?

Which diamond shape is more popular for engagement rings, square or round?

Round diamonds remain the most popular choice due to their brilliance and timeless appeal.

However, square-shaped diamonds, especially princess and cushion cuts, are also popular for their contemporary look and larger face-up area.

How does finger size impact the appearance of different diamond shapes?

Finger size can influence how big a diamond looks.

Wider fingers may require a larger diamond for the same visual impact, while slender fingers may make a diamond look more substantial.

Square shapes may look better on longer fingers, while round diamonds can suit a variety of finger types.

Can certain settings make a diamond look larger regardless of shape?

Choosing a setting that enhances the diamond's appearance can be an effective way to maximise visual impact.

Are square diamonds more expensive than round diamonds of the same carat weight?

Square diamonds, such as princess cuts, are typically less expensive than round diamonds of the same carat weight due to lower cutting costs and less wastage during the cutting process.

However, the price can vary based on the diamond's cut quality, colour, and clarity.
