What Is a Square Engagement Ring Called?

A square engagement ring is an engagement ring that features a square center diamond. Square engagement rings are often called Princess cut engagement rings, but this name isn’t entirely accurate.

While the Princess cut is the only true square, several other diamond shapes are considered square cuts. Cushion, Asscher, Radiant, and Emerald cut engagement rings are also called square engagement rings.

What Does a Square Diamond Mean?

Square diamonds often mean Princess cut diamonds, but a square diamond is any diamond shape that has a square or rectangular silhouette. Square diamonds often symbolize strength, power, and modernity.

History of Square Diamonds

Square diamonds are a relatively recent cut. Variations of square cut diamonds (Emeralds, Cushions, and Asscher cuts) are seen throughout history, but the square cut wasn’t officially defined until the 1960s.

Diamond cutting tools had evolved and it was now possible for cutters to create more complex diamond cuts. Linear diamond shapes were no longer limited to a specific faceting structure (step cuts). Diamond cutters started to create square diamond shapes with modified brilliant cuts. This is how the Princess cut diamond was created, and square cut diamonds were finally defined.

Types of Square Diamond Engagement Rings

There are several types of square cut diamonds to choose from for an engagement ring. The overall look and feel of your engagement ring will change depending on the square center diamond you choose. Most shapes lend themselves well to modern yet timeless styles, but some are better suited to vintage-inspired settings. Explore each traditional square diamond shape below.

How to Choose a Square Cut Diamond Engagement Ring

When choosing a square diamond engagement ring, consider the following.

Diamond Shape

The square diamond shape is the most important thing to consider when buying an engagement ring. Some square diamond shapes have step cuts while others have modified brilliant cuts.

Other shapes have a squarer, more modern look (like Princess cuts), while some have a more rectangular, historic appearance (like Emeralds). Each diamond shape has its own pros and cons, distinct style, and can vary in price. Choose the shape that suits your preferences and desired appearance.


Certain shapes hide color while others maximize their carat weight. Use the diamond 4Cs to determine the ideal diamond quality grade for your square diamond shape. A quality square diamond will have optimal brilliance and its coveted silhouette.

Ring Style

The setting and metal color you choose will greatly influence your ring style. Square diamonds have a naturally modern look, so consider whether or not you want the setting to enhance this or to create a different style.

To enhance the modern look of a square diamond while offering unparalleled security, consider a Bezel setting. Bezel set engagement rings are sleek, minimalistic, and will spotlight the unique square silhouette more than any setting.

Most square cut diamonds are contemporary shapes, but when combined with a Halo setting, you’ll have a vintage, heirloom appearance. Halo settings fully encircle the diamond to add security and brilliance.

Multi-Stone Square Engagement Rings

Engagement ring settings with several diamonds are particularly popular for square diamonds. Square diamonds like Emerald and Asscher cuts embodied the Art Deco era.

Art Deco engagement rings often feature multiple diamonds, such as Three Stone engagement rings. To enhance the size, brilliance, and Art Deco style of a square diamond, consider a multi-stone setting.

Gold Square Engagement Rings

White gold engagement rings are modern and sleek, further highlighting the contemporary look and feel of square diamonds.

Rose gold engagement rings are romantic and vintage-inspired, perfect for an heirloom design.

Platinum Square Engagement Rings

Platinum engagement rings are considered the ultimate indulgence, famed for their durability and strength. Platinum creates a lustrous sheen that pairs beautifully with sleek, modern square shapes. Platinum will highlight the elegance of whatever setting style you choose.

Which Wedding Band Goes With Square Engagement Rings?

The best wedding band for a square engagement ring will pair flush with the elongated center diamond to prevent scratches or chipping. This is particularly important for a Princess engagement ring set, as Princess diamonds have four sharp corners. A VRAI diamond expert can ensure that the two rings will sit comfortably together on your finger.

Protection aside, the best wedding band depends on your personal preferences and your engagement ring.

For shoppers seeking a diamond-accented ring set, start by considering your center stone. If you have a brilliant cut Princess, Cushion, or Radiant cut diamond, a pavé set or Round Brilliant cut diamond band might be best.

If you have an Emerald or Asscher engagement ring, consider pairing a Baguette diamond band for a modern yet Art Deco ring set.

A matching or contrasting plain metal band, like the Round Band or Flat Band, offers a more timeless and traditional ring set.
