Best Answer

If the diamond is a round brilliant cut, the measurement at the girdle of a diamond of this carat weight measures about 5.2 mm.

If the diamond is not a round brilliant cut, the measurement will be different.

It all depends on the shape you select. For e.g. a GIA certified around 0.50 carat measures width 5.13mm x length 5.11mm and a princess shape measures width 3.84mm x length 4.08mm.
