How many cut factor categories exist, and which two are among them?

• A. Two categories; weight ratio and durability are the factors
• B. Three categories; weight ratio and durability are among the factors
• C. Three categories; only color and clarity are considered
• D. Four categories; table width and girdle thickness are factors

Answer: (B)

In evaluating cut, factors are organized into categories to separate how the cut affects size, structure, and light performance. There are three cut factor categories. Two examples among them are weight ratio and durability, which show how much weight is preserved in the finished gem and how the cut influences the diamond’s strength and resistance to damage. The remaining category covers aspects related to optical performance and appearance, such as how the proportions and symmetry influence light return. That’s why three categories exist, and weight ratio and durability are indeed among the factors. The other options misstate the number of categories or pair cut factors with properties like color or clarity that aren’t cut-factor categories.
