The cut of the diamond will dramatically influence the radiance and sparkle so it is a very important feature to learn more about. Many mistakenly think that the cut only refers to the shape but this is not so. The cut has to do with the reflective qualities of the diamond. Simply said, you want to make sure that the light radiates out through the top of the diamond which is called the table and not through the bottom and sides of the gem. The higher grade of diamond cut you choose, the more sparkle and shine you will see. In round diamonds the cut refers to cut, polish and symmetry while in other shapes the cut actually only refers to polish and symmetry.
Polish and SymmetryThe polish has to do with the surfaces on the diamond. In a round diamond there are many different surfaces and for these to be without tiny cracks and blemishes the diamond needs to be well polished.
Symmetry is just what it sounds like. A more symmetric diamond looks better and in the lower cut grades you can even notice this with the naked eye. The symmetry of the diamond is more crucial when it comes to round diamonds. In other shapes it could be enough with the grade Good for it to look beautiful and harmonious.
The Categories of Diamond CutsThere are three main categories of diamond cut and each one will produce a different type of radiance. Sometimes it can be hard to see the difference between diamond cuts so it is important to use a good certificate and also work with a trusted dealer who has a trained eye to see what type of cut the diamond you are interested in has. To get maximum brilliance you want the light to go through the top of the diamond, the table, and then move from side to side before it comes back up through the top again.
Ideal CutIn an ideal cut the light will go through the table and then bounce from side to side in the pavilion (the middle area of the diamond) to come back up again. This is the perfect cut and it means that the brilliance of the stone will have amazing properties and the stone will simply look gorgeous to anyone. With this cut you can expect the type of sparkles that will make anyone look one more time in amazement.
If you see the expression Fine Cut it means something similar to Ideal Cut only that the distance between the table and the culet (the point) is shorter than what you would see in an Ideal Cut diamond.
Shallow CutA Shallow Cut Diamond should not be confused with a Fine Cut because the brilliance and sparkle is something completely different. The Shallow Cut diamond will not bring the light back up through the table again. Instead the light will make its way out through the bottom of the diamond and as a result a lot of shine and radiance is lost. This type of diamond cut is also called a poor cut since it doesn’t bring the reflecting light back to your eye in an effective way.
Deep CutThe Deep Cut is another example of a poor cut where the desired effect of sparkles is lost. In a diamond with a Deep Cut the light will travel from the table and bounce of one side of the pavilion and then make its way out the bottom. Since it doesn’t come back up through the table we are, again, dealing with a diamond where the poor cut hinders the amazing brilliance you want to see in your diamond.
Diamond Cut GradesDifferent grading methods have slightly different names for the cut grades but in general we are speaking about 4 different levels. Understanding the features of each Cut can help you make a decision for which diamond to buy. In the end of the day it is your personal taste that will matter the most but if you are looking for the sparkles you’d better stick to the higher grades!
1.Ideal Cut and Excellent Cut
If you are looking for maximum brilliance, Ideal or Excellent Cut is the grade you should go for. Ideal Cut and Excellent Cut diamonds are the most expensive ones but you will definitely get the desired reaction when you present a diamond with this cut!
The grading Very Good Cut is close to Ideal and Excellent Cut and it is a very good looking cut. The advantage to Very Good Cut is that their prices tend to be a bit lower. These diamonds deliver the brilliance and fire you expect from a beautiful diamond even if it is doesn’t come with maximum light performance.
Diamonds with Good Cut often come from a rough diamond where the cutter decided to keep as much of the original as possible rather than creating a smaller stone. This is due to weight calculations. The cutter decides to leave more of the original even if the quality of the cut is lower than in Excellent and Very Good. The diamond is still good looking but not like in the top cut grades.
4.Fair and Poor
In a Fair and Poor Cut it is the carat weight that matters. The light will not reflect well from this diamond so you won’t see the amazing shine and sparkles that exists in the other types of cuts. However, in some cases it will still make sense to go for a diamond with this cut. This can be done to keep the weight, enjoy the large stone and bring out its beauty in a proper setting.
