Girdle Thickness
Girdle thickness is an important measurement in diamond and gemstone evaluation. It refers to the outer edge or border that runs around the widest part of a cut gemstone. Think of it like the "belt line" of a diamond. This measurement is crucial because it affects both the gem's durability and appearance. Jewelers and gemologists regularly assess girdle thickness as part of their quality evaluations, rating it from extremely thin to extremely thick. The right girdle thickness helps protect the stone from damage while maintaining its beauty and proper proportions.

Example Interview Questions
Senior Level Questions
Q: How do you determine if a diamond's girdle thickness is appropriate for its size and shape?
Expected Answer: A senior gemologist should explain how they consider the diamond's overall proportions, weight, and shape to determine appropriate girdle thickness, mentioning how very thin or thick girdles can affect value and durability.
Q: What factors would you consider when advising a manufacturer about optimal girdle thickness during cutting?
Expected Answer: Should discuss balancing factors like weight retention, durability, and visual appearance, while explaining how different shapes and sizes require different approaches to girdle thickness.
Mid Level Questions
Q: What are the potential problems with extremely thin or thick girdles?
Expected Answer: Should explain that extremely thin girdles risk damage and breakage, while extremely thick ones can affect light performance and make the stone appear larger than its weight would suggest.
Q: How do you measure and grade girdle thickness?
Expected Answer: Should describe the standard categories from extremely thin to extremely thick, and explain basic measurement techniques using standard gemological tools.
Junior Level Questions
Q: What is a girdle in a diamond and why is it important?
Expected Answer: Should be able to identify the girdle as the outer edge of the diamond and explain its basic role in protecting the stone and affecting its appearance.
Q: What tools do you use to evaluate girdle thickness?
Expected Answer: Should name basic gemological tools like loupes and microscopes, and describe how they're used for basic girdle thickness assessment.
