CUSHION-CUT VS. RADIANT-CUT DIAMONDS: KEY DIFFERENCES

When it comes to finding your ideal engagement ring, choosing a diamond shape is one of the first and most important decisions you can make. After all, the diamond is the star of the show! At first glance, cushion-cut and radiant-cut diamonds can look very similar. However, there are a number of key differences between them that may make one a more attractive option than the other for you. Let’s explore how these diamond shapes compare, so you can choose the one that speaks to your style.

Shape

Also referred to as a pillow-cut diamond, the cushion-cut diamond features a square or rectangular face with rounded corners, resembling a soft, pillow-like shape.

The radiant-cut diamond similarly features a square or rectangular face; however, it has cropped corners, typically cut at a 45° angle. This gives the diamond a more angular, geometric shape.

 

Popularity

The cushion-cut diamond is the fourth-most popular diamond shape in the United States. Hugely popular in the 19th and early 20th centuries, the cushion-cut diamond is experiencing a resurgence, largely thanks to a myriad of celebrities seen sporting opulent cushion-cut diamond engagement rings.

The radiant-cut diamond is the eighth-most popular diamond shape in the United States. Designed in 1977 by Henry Grossbard, the radiant-cut diamond is a relatively new shape that is growing in popularity among celebrities and couples looking for a more modern diamond style.

 

Style

The cushion-cut diamond is adored for its vintage charm. The unique shape and curved, smooth corners of a cushion-cut diamond give it a soft, romantic look. The cushion-cut diamond is also celebrated for its remarkable fire (reflection of colored light).

The radiant-cut diamond is admired for its modern appeal. It combines the elegance of the emerald-cut diamond with the brilliance of the round-cut diamond to offer a bold look with exceptional sparkle. Its crisp, sleek appearance gives it a contemporary, geometric look.

 

Price

Cushion-cut diamonds and radiant-cut diamonds are similarly priced, with both typically costing less than a round-cut diamond of the same carat weight. This is partly due to the fact that both diamonds retain a large amount of the rough diamond during the cutting process, offering great value for money.

Settings

Both cushion-cut diamonds and radiant-cut diamonds are durable, versatile shapes that look beautiful in a variety of ring settings. For most styles of either shape, a four-prong ring setting will help keep the stone protected and hold it securely in place. For larger diamonds, a six-prong setting will provide added protection.

Some of the most popular settings for both cushion-cut and radiant-cut diamond engagement rings include:

  • Solitaire: A single stone takes the spotlight, showcasing the diamond’s unique shape.
  • Three-Stone: Two side stones flank the center stone, giving the ring extra character and shine.
  • Halo: A halo of smaller stones surrounds the larger center stone for a showstopping look.
