Cut
Cut grade assesses all aspects of the cut of a round brilliant diamond considering the following characteristics:
Face-up Appearance: the brightness, fire and scintillation (especially pattern) seen when viewing a diamond.
Design: the weight ratio of a diamond (which recognizes undesirable “thick makes”) and its durability (related to “knife edge” or extremely
thin girdles).
Craftsmanship: the care in execution that can be seen in the diamond’s polish and symmetry.

Cut Grading Systems assign one of five grades: Excellent, Very Good, Good, Fair and Poor
These grades describe overall cut quality. Each cut grade represents a range of proportion sets and diamond appearances that may conform, in different ways, to the characteristics of that grade.
