Girdle

What is a Girdle?

The girdle is the small area seperating the upper section (crown)  from the lower section (pavilion) of the diamond. 

On a  round brilliant diamond the girdle is scalloped with 16 hills and valleys. A thicker girdle contributes to its overall depth percentage. This greater depth may add weight and therefore cost without improving the diamonds face-up appearance.  Traditionally the girdle has a frosted appearance but some cutters will micro facet the girdle to give it a more finished look.

The girdle thickness is defined by ranges of the following terms:

Extremely Thin
Very Thin
Thin
Medium
Slightly Thick
Thick
Very Thick
Extremely Thick

Girdles not in the extremes of the scale are more desirable.
