# Rough girdle

A rough girdle has an irregular or granular girdle surface.

## In more detail

Do not confuse it with a bruted girdle, which is left with the surface from rounding. A diamond's girdle can look waxy to granular; in GIA's 1997 study, moissanite girdles were frosted, polished or striated.

## On a grading report

A blemish.
