Diamonds are graded based on an international “standard” system that involves inspecting the color of the diamond, the clarity of the diamond, the cut quality of the diamond and, of course, the carat weight of the diamond – known as the 4 C’s of Diamonds. While the carat weight, color and clarity rating of a diamond can play quite a significant role in the diamond’s price and appearance, people often tend to forget just how important the cut quality of a diamond also is. The cut quality of a diamond is a representation of the proportions of the particular diamond that is being inspected. And yes, the cut quality might have an impact on the physical appearance of the diamond, as well as on its final selling price.
Diamond Cut Grading System
During the grading process of a diamond, the appraiser will look at several aspects related to how well the diamond was cut originally before it was sent to the appraiser for its evaluation. During this inspection, the appraiser needs to consider the proportions of the diamond – such as the length to width ration of the diamond, as well as the table % and the depth %. Apart from the proportions, the appraiser also looks at the symmetry of the diamond’s facets. Other aspects are also considered, such as the diamond’s brilliance, which refers to the light reflection that the diamond exerts when a white light is placed upon it. The fire and scintillation, which is a term that refers to the sparkle flashes that can be observed when a light is moved across the particular area where the diamond is placed, also plays important parts in how the diamond’s cut is graded. Finally, the appraiser looks at the finishing details of the diamond – including the diamond’s polish and whether it has gone through a treatment procedure to fill cavities and to fix imperfections.
As you can see, many of these aspects regarding the cut quality of a diamond will determine how the finished product looks when placed in a ring. For example, a diamond with a poor brilliance, scintillation and fire rating will not look as good as one with good ratings in these areas. You obviously want the diamond you are going to buy to reflect a bright light (not too much, though) when light is shone upon it. You also want the diamond to have a good amount of sparkle without looking fake in lighted environments, especially when whomever is wearing the diamond is moving through the room. In the end, you really want the diamond to be impressive – something that should not be hidden away, but rather worn with pride and confidence, and shown off.
As a final tip, we also recommend paying attention to the cut proportions of the diamond. A diamond with a shallow cut will not reflect upwards. The same happens with a cut that is too deep, as the light is reflected through the bottom part of a diamond. You want an ideal cut to ensure the reflection are shone through the top of the diamond.
Diamond cut quality is a vital part of the standard grading system used to determine the value of a diamond, yet people often do not look at this particular value when they analyze a grading report. Many aspects related to the promotion and symmetry of a diamond is inspected when the cut quality of a diamond is being determined, which, in the end, could impact how the diamond looks and how much it costs.
