Color Grade
Color Grade is a key measure of a diamond's quality and value. It refers to how colorless or white a diamond appears, ranging from completely colorless (most valuable) to light yellow or brown. Diamond professionals use this grading system, which goes from D (highest/colorless) to Z (lowest/light color), to assess and price diamonds. Think of it like a rating scale that helps determine how pure and valuable a diamond is. When you see this term in resumes, it shows that the person has experience in evaluating diamond quality and understands this important industry standard.
