Introducing The Cushion Cut Diamond

It can be rather difficult to shop for a cushion cut diamond engagement rings, especially if the diamond will be used for an important event – such as in an engagement ring for a proposal. The diamond has to be perfect, but how do you really know when a diamond is “perfect”. Surely there is a universal system that tells you the “perfect” diamond is the one with the highest quality ratings, but this also means you will have to spend quite a lot of money on a gemstone. The truth is, the “perfect” diamond really defers from one individual to another. What may be “perfect” for you might not be “perfect” for someone else. Here we would like to introduce you to a particular diamond shape that is very popular in jewelry pieces – not only in engagement rings, but also in many other pieces of jewelry. This is the cushion cut.

The Cushion Cut

cushion cut diagramThe cushion cut was introduced approximately 200 years ago. During the first 100 years, it was considered the “default” shape for diamonds to be cut into and was also the most popular cut at the time. Today, however, the round brilliant cut has taken over its place, but the cushion cut still provides exceptional diamond beauty. This shape is a modified version of the square shape but, instead of having square corners, the cushion cut has corners that are rounded off. The shape is very similar to a pillow, which also explains the name of the cut.

When it comes to choosing the “perfect” cushion cut diamond, personal preference often plays a major part. Lumera Diamonds explain that, while some features, such as the cut quality of the diamond, can be guided, other features like size and the particular color of the diamond really depends on what the buyer prefers and, of course, what their budget allows. They do recommend opting for a cushion cut diamond with a table % in the range of 61 to 67, and a depth % between 61 and 67 as well. If these values are a little lower, it may still be a good buy, but the price should also be somewhat reduced as the cut cannot be promoted as “excellent” when these values are not in the ranges specified.

Note that some cushion cut diamonds represent a square shape, while others have a rectangular shape. If you opt for a square shape, try to find a perfect cut diamond with a length to width ration of 1.00 – 1.03. If you opt for a rectangular cushion cut diamond, then an “excellent” ratio would be 1.15 – 1.20. When the ratio of a rectangular cushion cut diamond reaches 1.08 – 1.09 or 1.31 – 1.50, then the ratio is considered “fair”, which is often not adequate for a higher-quality diamond – especially if your budget allows for a better diamond. If you do want to buy a cushion cut diamond with a cut that is in perspective and has good proportions, then try not to opt for a diamond with a length to width ratio that is rated as “poor”.


Cushion cut diamonds offer exceptional value for your money. The cut is very similar to the square cut, but features more rounded corners. The cushion cut has been named after its pillow-shape, and its design dates back to around 200 years. When buying such a diamond shape, there are many ways to get the most out of your money by simply choosing your preferred options wisely.
