A girdle is the outer edge or rim that runs around the widest part of a diamond. Think of it like the "equator" of the diamond that separates the top (crown) from the bottom (pavilion). When diamond professionals mention the girdle in resumes or job descriptions, they're referring to their experience in cutting, evaluating, or working with this crucial part of the diamond. The thickness and finish of the girdle are important factors in a diamond's overall quality and durability. This term frequently appears in diamond grading, cutting, and quality control positions.
