About Cushion-Cut Diamond

A brilliant display of 58 facets, soft rounded edges, and a dynamic appearance. Cushion-cut diamonds combine a square appearance with incredible sparkle. They are a highly versatile shape and can have a very different appearance and light performance from stone to stone, which we will examine shortly.

Cushion cuts are extremely elegant, with a distinctly vintage feel. They are also between 15-20% cheaper than a round brilliant of the same carat weight so they are an excellent choice for those desiring a sparkly diamond on a modest budget.

GIA Certified Cushion Cut Diamonds

The GIA gives reliable and accurate grades on color, clarity, polish, and symmetry for cushion-cut diamonds. The GIA does not issue cut grades on fancy-cut diamonds, as there is no agreed standard for how these diamonds should look. There are a variety of combinations that can be equally beautiful, making it impossible to standardize the cut grades.

However, the appearance of a cushion cut can be divided into 5 categories:

• Square cushion cut (best ratio 1:00-1:03)

• Rectangle cushion cut (best ratio 1:15-1:20)

• Cushion brilliant cuts (a facet pattern similar to a round brilliant)

• Modified cushion cuts/crushed iced cushion cuts (an extra row of facets beneath the girdle creates a crushed ice/crushed glass appearance)

• Chunky brilliant cushion cuts (display defined facet patterns and are typically considered ‘antique’ looking.)

With other cuts, you can often make an assessment of how the diamond will look based on the certification. Cushion cuts are best viewed in person with the guidance of a professional. They can look dramatically different depending on the modification as well as the traditional quality factors. Fortunately, our team is always on hand to help.
