The importance of a Diamond’s Cut

Not to be mistaken with shape, your diamond cut is an important characteristic to consider when purchasing a diamond. The cut will ultimately govern how well the light is refracted; giving the diamond it’s sparkle.

If you purchase a badly cut diamond then it will not refract the light as well and will not sparkle. Poorly cut diamonds will also give you a smaller spread for your selected carat weight.

Cut grades were developed by the GIA (Gemological Institute of America) during the 1940’s and 1950’s to enable independent labs to not only evaluate clarity and colour, but to check the structure of the diamond itself. For example, a round brilliant cut diamond will have 57 or 58 facets, which are precisely cut and defined.

While these are miniature in size, they are extremely important as they govern how well the diamond is going to sparkle.

It is important to ensure you select a well-cut diamond so that you get a good sparkle. You may be able to save a lot of money on poorer cut diamonds, but ultimately you will pay with a diamond that does not sparkle and lacks lustre.


Every diamond is graded on its cut quality and is given a grade, ranging from excellent to poor. The higher the cut grade, the better the fire and shine that is emitted from the diamond. Take a look at our diamond cut chart to understand each grade.

We would always recommend our customers to choose a diamond from an Excellent to Good cut. This will ensure you’re getting a good sparkle from your diamond. If you do want to look at the lower grade of cut, we always recommend looking at them in person before purchasing.
If you’re unsure, then please contact us on [email protected] or 0345 222 5009.


Diamonds graded as a Good cut reflect a good amount of light that is reflected into the diamond. A Good Cut diamond is value for money, and you will get a fantastic sparkle from your diamond. This cut is in the top 25% diamonds in the world.


Still considered a superior cut, a very good cut allows nearly as much light to refract through the diamond as much as an excellent cut. A considerably lower cost, a very good cut is a great choice to ensure a superior quality.


The best level of cut you can go for, it ensures the diamond is in perfect proportion and allows the light to perfect refract through one side of the diamond and out the other side. An Excellent or Ideal cut diamond will allow for optimum fire and sparkle.
