Cushion-cut diamonds are square or rectangular brilliant cuts with rounded corners and curved sides, resembling a pillow-like shape. Various cushion cuts are available today, ranging from antique to modern. As a popular diamond cut, multiple variations suit every personal preference.

The History

Although a modern favorite for engagement rings, the cushion-cut diamond design dates back to the 1700s. An antique cut, known as the “old mine cut,” laid most of the groundwork for today’s popular square shape. Stonecutters in Brazil admired the old mine cut because they could retain the stones’ carats.

Then, once diamonds were found in South Africa, the old antique mine cut received its name, as it was produced at “the old mines.” This popular diamond cut was square with rounded corners and 58 facets (flat faces on the diamond). The modern-day cushion developed much of its nature from the ancient cut but incorporates the round brilliant diamond aspects.

Cushion Brilliant or Standard?

Although more popular in their original square form, modern cushions come in standard and modified categories.

  • The standard cushion resembles the old mine cut, bringing an antique look through its classic square shape. It boasts broader facets and sometimes rounded sides. It’s scarce, however.
  • Cushion brilliant mixes everything you love about the original cushion cut with that of the round brilliant. This cut has extra facets and is thus a modification of the standard.

Square or Rectangle?

Personal preference and style are the most important aspects to consider when purchasing a cushion cut diamond. The two most significant factors that make cushion cuts unique are the length-to-width ratio and facet style.

The square cushion cut is the most popular choice for engagement rings, earrings, bracelets, and other jewelry pieces. For instance, the more equal the length and width, the more the diamond will have a smooth, seamless look for dainty fingers. We recommend seeking ratios between 1 and 1.05 if you want the square appearance.

Rectangular cushion cuts are rare but not impossible to create or find. However, the elongated shape will look stunning on shorter fingers. Look for a length-to-width ratio of around 1.1 to 1.2 to achieve the rectangular shape.
