If you’ve done some research on diamonds, you have probably heard of the 4 C’s: color, cut, carat, and clarity. Cut is one of the most important aspects of a diamond.  It is responsible for the sparkle, shine, and overall wow factor that makes diamonds so popular!

Cut or Cut?

There are actually two types of cut when referring to a diamond. There’s the cut that means a diamond’s shape, for example, round brilliant, princess cut, and oval. When deciding on the shape of a diamond, it’s all a matter of personal preference, what shape do you and your partner prefer? But the other type of cut is more technical. It refers to the proportions, finish, symmetry, and polish of a diamond, all of which are determined by the science behind cutting diamonds. This is the type of cut we will be talking about today.

What makes cut so special? Well, cut is what turns rough diamonds mined from the Earth into the beautiful gems you see in jewelry every day. The cut grade refers to the symmetry and proportions meaning length, width, and depth. It also refers to how a diamond is finished and polished to enhance the way light reacts with the stone. All of these are responsible for how well a diamond sparkles and shines.

Cut Grade

A diamond that has been given an excellent cut grade will give the maximum amount of brilliance and sparkle because the facets, or the surfaces on the geometric shape of the diamond, capture light and reflects it around perfectly. On the other hand, a diamond that is not cut well will look lifeless, dull, and almost dead because the light entering the diamond does not reflect the same way.  Picture two diamonds side by side, they both are the same carat weight, color, and clarity, but one has an excellent cut grade and one has a poor cut grade. These two diamonds will look completely different. Why? Because the poor cut diamond does not have any sparkle or life to it where the excellent cut diamond will have pizzazz and fire.

Poorly cut diamonds may have a tall and skinny, or a short and wide shape. In these diamonds, the light enters through the top and exits out the bottom giving them a dull appearance. With an excellent cut diamond, the light enters the top and bounces around the facets, before reflecting back through the top of the diamond to give it that maximum brilliance and fire.

Cut Grading Scale

The majority of the loose diamonds sold today are certified by a gemological lab such as GIA, EGL, or IGI. A round brilliant diamond will receive a cut grade that is printed on the diamond certificate provided by the lab. At Steven Singer Jewelers, all of our loose diamonds are certified from a reputable lab. Each diamond is hand-picked and is reviewed by our team of expert jewelers to ensure that every stone that enters our inventory has maximum life and sparkle.
