Do Cushion Cut Diamonds Appear Smaller in Size?

Cushion cuts have a deeper cut, sometimes making them appear smaller than other shapes with the same carat weight. If you prefer a cushion cut diamond, consider choosing a higher carat weight to achieve your desired size. 

How Can I Make A Cushion Cut Look Larger?

Cushion cut diamonds may appear smaller than their carat weight due to their deeper cut. To maximize perceived size, consider choosing a cushion cut diamond with a slightly shallower faceting or setting it in a halo engagement ring. Elongated cushion cuts provide more finger coverage and often make the diamond look larger. 

History And Evolution Of The Modern Cushion Cut Diamond

The modern cushion cut is influenced by the Old Mine diamond cut from the 1700s. In the 1800s to early 1900s, the Old Mine cut was the prevalent diamond shape before the round brilliant cut gained popularity. This cut originated due to diamond mining shifting from India to Brazil in the 1700s. Brazilian stone cutters mainly used the Old Mine cut as it preserved carat weight well for the rough crystals commonly found in Brazilian diamond mines. Old Mine cut diamonds had a squarish shape with rounded corners, a high crown, and a small table facet. Despite not having the brilliance of today’s standards, this style offered impressive sparkle. The cut prioritized weight retention and speed. 

Famous diamonds like the Hope and Regent diamonds showcase this historic cut. The Regent diamond, a 410-carat diamond from India dating back to 1701, is a remarkable example of the early Old Mine cut. The Hope diamond is a 45.52 carat blue diamond that is famous the world over.

What To Look For In A Cushion Cut Diamond:

When looking for a cushion cut diamond, consider the following factors to ensure you get a beautiful and high-quality stone: 


Look for a well-proportioned cut with a balance of brilliance and fire. The facets should be symmetrical, and the diamond should have excellent light performance. 


Choose a diamond with an eye-clean clarity grade, meaning it has no visible inclusions to the naked eye. A clarity grade of SI1 or higher is usually a good balance of quality and price. 


Aim for a color grade that matches your preferences and budget. Generally, diamonds in the near-colorless range (G to H) appear white and offer good value.  

Carat Weight

Determine the carat weight based on your desired size and budget. Remember that a deeper cut can make the diamond appear smaller, so consider a larger carat weight if you prefer a bigger look. 


Ensure the diamond has been independently certified by a reputable gemological laboratory like GIA, IGI, or AGS. This certification verifies the diamond’s quality and authenticity. 

Faceting Style

Decide between a traditional cushion cut with distinct large facets or a “crushed ice” cut with smaller, more scattered facets. Choose the style that appeals to your taste and preference for sparkle. 

Length-to-Width Ratio

Determine if you prefer a square or elongated cushion cut by considering the length-to-width ratio. Select the ratio that complements your desired aesthetic. 


The setting you choose for the cushion cut diamond can influence its overall appearance. Consider a halo setting or side stones to enhance the diamond’s size and sparkle.
