Girdle Thickness refers to which dimension of a diamond?

Explanation:
Girdle thickness is the width of the girdle—the measure of how thick the belt around the diamond is, from its inner surface to its outer surface. This is a cross‑sectional dimension around the stone, not a vertical height (which would be the crown height) or pavilion depth, and it’s not the girdle’s length around the perimeter. In practice, girdle thickness is described as extremely thin to extremely thick and affects durability and overall proportions. That width of the girdle is the concept being tested.
