October 03, 2023

What is a cushion diamond? The cushion cut diamond, often regarded as one of the most sought-after diamond shapes, is a unique fusion of the traditional square or rectangle cut and contemporary aesthetics. With its softly rounded edges, it evokes the image of a plush pillow. This harmonious combination of classic and contemporary design elements has made cushion cut diamonds a preferred choice for those yearning for timeless elegance complemented by modern sophistication.


What Is the History of a Cushion Cut Diamond?

The story of the cushion cut diamond traces back to the 1700s when stonecutters in Brazil first introduced the old mine cut. This antique cut, with its square shape and rounded corners, featured 58 facets. Notably, the old mine cut was prized for retaining a high carat weight, making it a popular choice during its era.

The 4Cs & the Cushion Cut

Cut:Cushion cut diamonds exhibit a slightly curved outline, and their length-to-width ratio typically ranges from 1.00 to 1.05. However, some variations can be more elongated, with proportions closer to 1.20 or 1.30. There are two different styles for cushion cut diamonds:

  • Standard Cushion Cut Diamond: Standard cushion cut diamonds resemble the old mine cut, characterized by chunky facets and a smaller table. These features give them a charming vintage or antique aesthetic.
  • Modified Cushion Cut Diamond: On the other hand, modified cushion cut diamonds bear a striking resemblance to the round brilliant cut. They boast an additional row of facets, imparting a dazzling, almost "crushed ice" appearance.

Color: Cushion cut diamonds tend to retain more color, making them an excellent choice for fancy colored diamonds. If you're seeking a colorless diamond, aim for a grade of G or better.

Clarity: Due to their open table, cushion cut diamonds can reveal imperfections more readily. Therefore, selecting a diamond with at least VS2 clarity or SI1 clarity is advisable, but not lower.

Carats: Elongated cushion cut diamonds offer a larger surface area, so even at the same carat weight, they appear larger than their square counterparts. 

When choosing a cushion cut, remember to consider factors such as depth, table percentage, polish, symmetry, and length-to-width ratio, which should align with your personal style and preferences.


Cushion Cut Diamond Prices

The price of a cushion cut diamond can vary significantly based on multiple factors, including the 4Cs (cut, color, clarity, and carat weight) and whether it's a fancy color or colorless diamond. Generally, cushion cuts are approximately 20-30% more affordable than round cuts, with one-carat stones typically ranging from $3,000 to $7,000, but you can expect to pay more for diamonds with higher grades, larger carat sizes, or some fancy colored diamonds.

Cushion Cut Advantages & Disadvantages

As with any diamond shape, individual preferences play a pivotal role in choosing a cushion cut. Here's a breakdown of the advantages and disadvantages:


  • Durability: The rounded edges of cushion cut diamonds make them less prone to chipping.
  • Brilliance: Cushion cuts exhibit a high level of brilliance and fire, creating a dazzling display of light.
  • Popularity: This cut enjoys immense popularity, resulting in a vast selection to choose from.
  • Affordability: Cushion cut diamonds are often more budget-friendly than brilliant round cuts.


  • Color Retention: Cushion cuts retain more color, so consider diamonds in the D to G color range to avoid a yellowish tint.
  • Clarity: Imperfections are more noticeable due to the open table.
  • Elongated Varieties: Elongated cushion cut diamonds are relatively rare and might be more challenging to find.
