Diamond Shape vs Cut:
In the first place, it is important to realize that the term "cut" may refer to the overall cut quality or the shape. While the idea of diamond shape is pretty easy to grasp, the subject of cut quality is more difficult.
As a matter of fact, the cut quality of your diamond will dictate the volume of light return and the intensity of the sparkle. Generally speaking, the offset for the crown and pavilion angle are the most critical components. However, the relationship between the table diameter and the crown angle will affect the sparkle factor. It can also affect the overall appearance of the diamond, especially in terms of the arrows pattern.
Needless to say that we have recommendations for each diamond shape. Therefore, we have created diamond buying guides for the most popular diamond shapes:
