Cushion Cut Diamond Vs. Round Diamond

The sparkle of a cushion-cut diamond is more subtle than that of a round diamond. In addition, it has 58 facets, as opposed to the 57 facets of a round diamond. The final decision between a round or Cushion cut depends on personal preference and taste. Either one is stunning and represents an excellent investment. Please continue reading to learn more about each shape and its advantages before deciding. It’s also important to remember that diamonds aren’t just for engagement rings anymore!

Generally, a cushion cut diamond has slightly less radiance than a round cut diamond. This is because the face of a cushion cut is more petite and carries the body’s weight under the girdle. On the other hand, round diamonds have a higher sparkle and are therefore more popular. The cut of a round diamond affects its brilliance, resulting in a diamond with more excellent overall brightness.

Another essential factor to consider is the concept of symmetry. Excellent symmetry is found in a cushion-cut diamond, which is symmetrical from all angles. Both the corners and the sides must be mirror images of one another. One other consideration is the girdle’s thickness, as a girdle that is too thin can make the stone more brittle and susceptible to chipping. As a result, it is recommended that you select an exceptionally symmetrical cushion cut. This will be a conversation starter for any occasion.

Cushion-Cut Diamond

Cushion cut diamonds, like old mine, cut diamonds, are shaped like a square with cut corners (or a cushion), but they have modern brilliant-cut faceting. Cushion-cut diamonds are considered a vintage style because they evolved from an ancient diamond shape. Cushion cut diamonds (also known as old mine cut diamonds) have a square cut with rounded corners, similar to a pillow (hence the name). This classic cut has been around for almost 200 years and was the most popular diamond shape for the first century of its existence (similar to the round cut today). The cushion-cut diamond was the de facto diamond shape until the early twentieth century.

Modern cushion cuts return light in a chunkier pattern than traditional cushion cuts. When combined with the enlarged culet (which was desired for the pattern created when viewed through the table), this resulted in a unique look that is highly sought after by antique diamond dealers today.

Round Cut Diamonds

Round diamonds are the most common and traditional diamonds given as a symbol of commitment. They are brilliant-cut because they have a classic uniform and symmetrical shape with 58 facets. Color and inclusions appear better in round-cut diamonds than in other fancy shapes due to the faceting. Round diamonds are so famous that they account for more than half of all diamond purchases; you’ll almost certainly see a round diamond engagement ring if you look around. But, if you’re considering purchasing a loose diamond in this shape, what do you need to know? We break it all down, from setting options to ideal measurements, cost estimates, and more.

Cushion Cut Diamond vs. Round Diamond

When choosing between a cushion cut and a round-cut diamond, personal preference is the most crucial factor to consider. The affordability of cushion-cut diamonds, on the other hand, has swayed many. Cushion cut diamonds are an excellent, beautiful option if you like the look of both cushion cut and round diamonds but want a more affordable diamond. Alternatively, if you’ve already decided that cushion cut diamonds are the way, their low price is just a bonus.

However, if you know you prefer round diamonds, we recommend not being swayed by the Cushion cut diamond’s lower price. The most important aspect of a diamond is that you adore it. This is especially true when choosing a diamond for your diamond engagement ring. If you want a round diamond engagement ring, a cushion-cut engagement ring will never make you happy. A diamond is a long-term investment that you will enjoy for a lifetime. So, if your heart tells you that a round diamond is the one for you, we recommend you listen to it and choose the diamond shape you know you’ll love for years to come.

Whether you prefer a round cut or a cushion cut diamond, both are beautiful and classic choices for your jeweler. However, if you have to choose between these two diamond shapes, which one should you go with? This post will go over everything you need to know about the differences between round-cut and cushion-cut diamonds. This discussion will look at how these diamond shapes compare in five categories: style, radiance, size, ease of selection, and price.


Let’s start with the differences in style between round and cut cushion diamonds.

Round diamonds are a classic and traditional diamond shape in terms of style. Round diamonds are also the most popular shape for engagement rings, diamond rings, and a variety of other diamond jeweler. Round brilliant diamonds account for roughly half of all diamonds sold today.

On the other hand, Cushion-cut diamonds are a unique, vintage-style shape. Cushion cut diamonds are a modern take on an antique diamond shape known as the old mine cut. Cushion cut diamonds, like old mine, cut diamonds, are shaped like a square with cut corners (or a cushion), but they have modern brilliant-cut faceting. Cushion-cut diamonds are considered a vintage style because they evolved from an ancient diamond shape.

Cushion cut diamonds, unlike many other rectangular or square-shaped diamonds, have very different styles, such as princess cut, emerald cut, radiant cut, and Escher cut diamonds. Cushion diamonds, like emerald and Escher, cut diamonds, have a vintage look to them. Their style influences, on the other hand, are very decade specific. Escher-cut diamonds have an Art Deco era vintage style, while emerald-cut diamonds have a retro era vintage style (think old Hollywood) (think: The Great Gatsby). On the other hand, Cushion-cut diamonds have a more romantic, antique vintage appearance. On the other hand, Cushion cut diamonds are stylistically distinct from princess cut diamonds and radiant cut diamonds. Princess diamonds and radiant cut diamonds are both very fashionable.

When comparing the styles of round and cushion-cut diamonds, keep in mind that there is no “best” style. It’s just a matter of personal preference when choosing the right style for you. Choose a round diamond if you want an ultra-classic diamond. Choose a cushion-cut diamond if you like the romantic, vintage look of the shape.


Both the round cut and the cushion cut diamonds are stunning and brilliant. The way they’re cut, however, makes them sparkle uniquely.

When light strikes a diamond, it reflects and refracts it before emitting it, which gives a diamond its sparkle. The sparkle emitted by a diamond is known as scintillation in technical terms. The scintillation of a diamond is made up of two types of light: white light (called brilliance) and rainbow light (called fluorescence) (called fire).

The amount and type of scintillation in the round and cushion-cut diamonds differ, and the overall amount of scintillation in round diamonds is higher. One of the reasons they are so popular is that they are the most brilliant diamond shape. Then there are cut cushion diamonds, which are still brilliant but not as brilliant as round diamonds. They do, however, have more fire due to their more significant facets.

Many people prefer the high fire of a cushion-cut diamond, while others prefer round diamonds’ high overall brilliance.


Finally, consider the cost difference between rounds and cushion diamonds. Cushion-cut diamonds have a clear advantage over round diamonds in this category. The most expensive diamond shape is the round brilliant cut diamond. One reason for this is that creating a brilliant round diamond generates more waste, forcing diamond cutters to raise their prices. Another reason is that brilliant round diamonds are trendy and sought after. Diamond companies price round diamonds higher due to their popularity, which means jewelers must do the same.

So, how much cheaper are cut cushion diamonds compared to round diamonds? If two cushion cut and round diamonds have the same carat weight and qualities, the Cushion cut diamond will cost between 25% and 50% less. Cushion-cut diamonds have seen a slight increase in price as they have become more popular. They are, however, still one of the most cost-effective diamond shapes.

Is a Cushion Cut Diamond Preferable to a Round Diamond?

Depending on the cut, cushion-cut diamonds can have a slightly larger table (top) per carat than brilliant round diamonds. Additionally, they have more significant facets, giving the impression that they are more extensive. On the other hand, round diamonds are more brilliant than Cushion cut diamonds, and our eyes are more likely to perceive higher brilliance as greater size.

How do Round & Cushion Shapes Compare?

The round cut is the most popular shape for engagement rings because its cuts maximize light reflection, brilliance, and brightness. There are 58 facets in a round brilliant cut diamond, and its 58-facet cut is split between the crown (top), girdle (widest part), and pavilion (bottom) (base).

Cushion cuts combine the symmetry of a radiant cut with the energy of a round brilliant. Because their 58 facets are larger than round cuts, they are slightly less sparkly. More significant facets can reveal clarity inclusions, so look at the diamond plot on the certificate to see where they are. If you insist on a cushion cut and need to conceal an imperfection, a crushed ice diamond, which has more imperfection-masking facets, might be a better option.

Is it True That Cut Cushion Diamonds Are More Expensive Than Round Diamonds?

Round cut diamonds are more expensive than Cushion cut diamonds because round is the most expensive diamond shape. Do you want to know how these shapes compare in terms of price? A cushion cut diamond will typically cost 25% to 50% less than a round cut diamond of the same carat weight and quality.

What is the Most Effective Method for Cleaning a Diamond?

You are cleaning diamond jewelry with household cleaners. The simplest way to keep your diamonds spotless is to soak them once or twice a week in a gentle and mild de-greasing solution, such as warm and diluted dish soap water or an ammonia-based household cleaner.

In a shallow bowl, combine 1/2 cup white vinegar and two tablespoons of baking soda. Make sure the baking soda is completely dissolved before mixing the solution. Soak your diamond ring for two to three hours in the solution. Then soak your ring in cold water and dry it with a soft cloth.

What is the Price Difference Between a Round & a Cushion?

Cushion cut diamonds are typically 25 percent less expensive than round cut diamonds. Because more material is lost when jewelers shape a rough stone into a round diamond, the cost of each carat retained is higher. Some of our favorite round and cushion cut engagement ring styles are listed below. As you can see, these cuts are incredibly versatile, allowing them to be used in both minimalist and artisanal designs. As you shop, keep in mind that there is no wrong choice if you follow your taste.


The cushion-cut diamond has a long and illustrious history. Cushion diamonds have been a popular shape for more than two centuries. They experienced a period of decline in the nineteenth century but have experienced a resurgence in the twentieth century. In the 1920s, a diamond cutter by the name of Marcel Tolko sky perfected the cushion cut, laying the foundation for the future development of optimal diamond cuts. An old mine cut tended to have a large culet, which Tolko sky eliminated by lowering the height of the crown and increasing the size of the table. The symmetry of the situation is the next vital factor to consider. To make an informed decision about whether you should purchase a round or cushion-cut diamond, you should consider a few things. Even though the center stone of your engagement ring is set with a round diamond, a cushion-cut diamond will still look stunning in your hand. And the only way to know that it will sparkle is to purchase a ring for you.
