Cut is the only element of the 4 C´s influenced by the human hand and is often considered the most important.
Precise workmanship is required to cut a diamond so its proportions, symmetry, and polish maximize brightness and fire.
If the diamond is not well cut, it will not interact with light as it should.
Each grade is evaluated according to 3 parameters: proportions, polish and symmetry. The Cut is divided into 5 grades:
Excellent, Very Good, Good, Fair and Poor.
