While it is important to consider many components when assessing the overall cut appearance and quality of round brilliant diamonds, an individual’s preferences also play a role. Because each cut grade represents a wide range of proportion sets, individuals have the freedom to choose which particular appearance they prefer within the grade range.
The diamond industry as well as the public can use cut along with color, clarity, and carat weight to help them make more informed decisions when assessing and purchasing round brilliant diamonds.
CUT VS. SHAPE
People often use the words cut and shape interchangeably. They think of cut as the shape or outline of the diamond, rather than the arrangement of facets needed to create an attractive face-up appearance.
Round is the shape used in most diamond jewelry. All other outlines are known as fancy shapes. Examples of traditional fancy shapes include the marquise, pear and oval. Hearts, triangles and a variety of others are also gaining popularity in diamond jewelry.
