A cushion-cut diamond is essentially the elegant combination of a square cut and rounded corners, giving it the charming appearance of a cozy cushion. It is precisely this appearance that earned it the name “cushion cut.”

The following are the main characteristics that distinguish a cushion-cut diamond:

• Square or rectangular shape
• Rounded edges
• Similar to the princess and round brilliant-cut diamonds, the brilliant-cut style
• Vintage and antique look, evoking a sense of timeless elegance

Nevertheless, there are some things to think about carefully before making your final choice. This article aims to furnish you with the essential factors to examine during this process.

Cushion Cut Diamond Buying Guide: Things to Consider

1) 4Cs of Diamond

Irrespective of the diamond you wish to purchase, it is essential always to evaluate the 4Cs of the diamond. While the “cushion cut” is indeed a significant factor, making the best purchase also relies on considering the other three Cs.

That is why the 4Cs, comprising Cut, Color, Clarity, and Carat weight, hold significant importance when evaluating cushion cut diamonds. A well-cut diamond maximizes brilliance and sparkle, while a colourless or near-colourless grade enhances its beauty. Optimal clarity ensures a visually appealing diamond without visible flaws, and the carat weight determines its size. By considering and balancing these factors, you can make an informed decision and find the perfect cushion-cut diamond that aligns with your preferences and requirements.

2) Cushion Cut Diamond Ratio

Cushion-cut diamonds frequently have a 1:1 length-to-width ratio and are perfectly square. But these diamonds can also be found in different ratios, which makes them appear more square or rectangular. To achieve a more square look, opt for a ratio between 1.00 and 1.09, while for a more rectangular appearance, the best ratio for cushion cut diamond is between 1.15 and 1.50.

It’s important to note that there is no universal “best” ratio for cushion-cut diamonds since it ultimately depends on personal preferences. Nevertheless, the most popular ratio range for cushion-cut diamonds falls between 1.10 and 1.20.

3) Cushion Cut Diamond Depth

In a cushion cut diamond, the depth and table percentages are very important to guarantee the best possible light reflection. For the best results, experts typically advise selecting diamonds with depth and table percentages below 70%. 

These percentages determine how well light is refracted and reflected within the diamond, ultimately affecting its brilliance and sparkle. Additionally, it is important to note that while depth and table percentages are important factors, other aspects such as symmetry and polish should also be considered when choosing a cushion cut diamond. 

4) Hearts and Arrows

If your quest is for the finest cut, you might find yourself captivated by cushion-cut diamonds featuring Hearts and Arrows. While these cushions exhibit remarkable performance, it's important to keep in mind that cushion-cut diamonds can still exhibit brilliant performance even in the absence of the hearts-and-arrows pattern. In addition, the hearts-and-arrows pattern is usually only noticeable on "chunky" cushions; people who like the "crushed ice" appearance should stay away from hearts and arrows.

5) Shape Appeal

Cushion-cut diamonds are available in a range of shapes, from nearly square to nearly round. The best option is to choose a visually pleasing medium ground with gently curved sides and rounded corners. To ensure you get the desired shape, it’s crucial to have a clear image of the diamond. If the shape appears off or doesn’t meet your preferences, it’s best to refrain from making the purchase.
