What is the primary goal of colored diamond color grading?

• A. To maximize carat weight.
• B. To arrive at a repeatable, consistent grade.
• C. To fit current fashion trends.
• D. To rank diamonds by shape.

Answer: (B)

Color grading aims to be reliable and comparable. The primary goal is to arrive at a repeatable, consistent grade so that graders describe a diamond’s color in the same way under standardized conditions, enabling meaningful comparison between stones and over time. This is achieved through controlled lighting, a defined grading scale, and reference master stones to minimize subjectivity. The other options don’t address this goal: carat weight measures size, fashion trends don’t define how color is evaluated, and shape is about cut and form, not color.
