When and why the cushion-cut diamond was introduced to jewelry?

Although being part of the fancy cuts, the origins of the cushion cut date back to the early 1800s, when this cutting technique appeared for the first time and quickly became one of the most renowned diamond shapes during the 1800s and the 1900s. Its cute ‘pillow shape’ features soft edges, made to capture and reflect a spectrum of warm, candlelight colors. In fact, this particular diamond cut was specially designed to make the stone glitter with an extraordinary inner incandescence. Another interesting ‘purpose of existence’ of the cushion cut is to satisfy the needs of jewelry enthusiasts who are fanatic for the combination of round and square diamond jewels in vintage style.

The average number of facets in the cushion-cut diamond is 60. Normally, its length-to-width ratio is 1.00, which is the cause for its alluring square shape that wins the heart of everyone with a good taste for fine jewelry.

Why to choose a cushion-cut jewelry adornment?



Diamonds sculpted in the popular ‘pillow shape’ are unique and they come with special allure and elegance that no other cut can provide. Moreover, the authenticity of these diamonds evokes the feelings of superiority, as this is how this cut has started to build its reputation in the graceful jewelry world.



There were also times in the history of cushion-cut diamonds where this jewelry style was very hard to find. Thus, the only ways to enrich your collection with a piece in cushion cut were either an estate sale or an antique jeweler. However, the cushion cut made a huge come back in the last few decades and today, it represents one of the most fashionable styles of diamond jewelry.

Thanks to its immense popularity, the cushion cut  can be seen today in a broad spectrum of rings, necklaces, earrings and bracelets in different designs, so there is absolutely no chance that you won’t find one at your preference.



Cushion-cut jewelry, particularly when it comes to cushion-cut rings, are nothing, but the perfect everyday option for ladies with an active lifestyle. And it is all thanks to the soft, rounded, pillow-like edges of the diamond that make the entire jewelry piece not prone to chipping nor catching on hair and clothes.

What could make you dislike a cushion-cut jewelry adornment?



One of the biggest drawbacks of the diamond in cushion-cut is its level of fire and brilliance. In other words, the fire that this cut provides is slightly more ‘toned down’ when compared to some other diamond cuts. This characteristic comes as a result of the fact that the cushion cut has been primarily developed to sparkle under the dimmed flames of candlelight, hence, the reason why the cushion-cut diamond could never shine as intensely as the diamond in round brilliant or asscher cut, for example.

But, for cushion-cut fans, this is the feature for which this diamond shape is most favored. Its special ability to disperse light creates a captivating effect of tender, kaleidoscope rainbow of warm colors – a property that is hard to say no to.



Generally, the pillow shape comes with large facets and the biggest problem of large-faceted diamonds is that they could potentially highlight the gem’s existing blemishes or inclusions. This way, the diamond could consequently draw attention  to its color tints, especially if the stone’s carat size is larger than 1.0 ct.

How to choose the right cushion-cut diamond?

Having all of its pros and cons at your disposal, now you can be ready to buy the perfect cushion-cut jewel, without any shadow of doubt or concern. To make your selection even easier, we suggest you to look for a diamond that will feature the following grades:

- A GIA diamond clarity grade of L2 and above. (VS2 would be the ideal and most affordable grade).

- A GIA diamond color grade of G and above.

For diamonds with smaller sizes, you can also go for lower grades of the aforementioned values, because any existing flaws in the stone would be almost invisible. As we have just mentioned, this won’t be the case for diamonds larger than 1.0 ct., so pay special attention to this feature when making your ultimate cushion-cut jewelry selection.

Which settings fit best to the cushion-cut diamond?

By far, the one and only diamond setting that has proved to go flawlessly well with the cushion cut, is the 4 prong setting. What makes this setting perfect for cushion-cut diamonds is the ability to hold and protect the stone securely without blocking the light to reflect and refract from its surface. Since diamonds in cushion cut tend to come with reduced levels of fire and brilliance, the 4 prong setting works perfectly in maximizing these qualities.

The 6 prong setting can be also seen in cushion-cut diamonds, but this setting is generally used for longer and larger gems that feature a more rectangular pillow shape.

Modern diamonds in cushion cut might also promote the bezel setting, although this setting is not much favored for this purpose, due to the fact that by wrapping the gem entirely, the bezel blocks the light to enter the stone. Hence, it contributes to subduing its grade of fire and brilliance, which is certainly not recommended for cushion-styled diamonds.
