The essentials you must know when choosing a Diamond cut

Among the 4C`s, one of the most important is the cut, which profoundly affects how a diamond looks and is one of the most important in determining its price. Consequently, in order to ensure that you make the right decision and one that you will always be happy with, it is imperative that you understand the basics of the Cut grade. The following is a comprehensive guide to everything you need to know when it comes to the diamond cut and how it can help you buy the right diamond. For the sake of keeping our summary concise and easily accessible, we have separated it into two sections, one for Round diamonds and the other for every other diamond shape.



The Cut grade on a diamond`s lab certificate is officially only assigned to round diamonds. Diamond certifiers, like IGI, award the grades, from the highest, "Ideal", then "Excellent", "Very Good", "Good" and so on, depending on how closely they match the established dimensions for that specific ct size. Round diamonds are the only cut where all the dimensions can be defined by a set of Ideal measurements and then compared against a set of actual measurements.



It may be challenging to tell the difference with a naked eye between an "Ideal" cut and an "Excellent" cut or between an "Excellent" cut and a "Very Good " cut. However, comparing the top and bottom grades, "Ideal cut" and "Very Good cut", you will start to see a difference in sparkle. To summarise, the cut of a diamond determines how well it absorbs and scatters light, with lower cut grades wasting more light from the side and, as a result, diminishing its sparkle.

As you may have noticed, the price increases slightly as you advance up the cut grades. It is generally recommended to go for a larger ct stone by sacrificing a cut grade when you want to stay within your budget since the size is easily visible to the naked eye, whereas the sparkle must be compared with other stones to notice a difference.

Budget-constrained individuals might want to consider a "Very Good" cut, which will enable them to buy a good-sized stone. Otherwise, sticking to an "Excellent cut" stone is recommended if you want to obtain a sparkling diamond for a great deal.

The essentials you must know when choosing a Diamond cut


In contrast to Round diamonds, `fancy shapes` do not have any standard dimensions to compare with because their dimensions can vary widely. For instance, some Oval diamonds are more elongated while others are more rounded, or a Cushion diamond can either be squarish or more rectangular. Every shape except rounds falls under this rule. Hence, diamond certifiers don`t award "cut gradings" to diamonds other than Round shapes.


A cut grade is something we know that our customers value very much, as it can help them determine if a specific diamond is suitable for them or not. Our gemologists at NOVITA DIAMONDS have developed a set of custom formulas that will allow us to assign an equivalent cut grade for every other shape. Even diamonds that are not round will now have a cut grade on our website for the benefit of our customers.

In light of the fact that we are only able to grade diamonds that we have direct access to, only our showroom stones will be given a `cut` grade by us. As it stands, we simply do not have the resources to be able to give similar cut grades to overseas diamonds. In the event that you are interested in purchasing an item that is not round and is not available in our showroom and would like more information regarding its cut, one of our gemmologists will be happy to answer your questions; simply contact us, and we will get back to you as soon as possible.
