The overall condition of a finished diamond's faceted
surfaces, including how smoothly the facets have been

Describes the alignment of the facets of the diamond. If
facets are misaligned, the diamond may poorly reflect
light. Symmetry is graded from Ideal / Excellent, Very
Good, Good, Fair, or Poor. Symmetry grades of Good or
higher have the least effect on the brilliance of the
diamond and are suitable for the finest quality jewelry.
Certain gem labs, such as Gemscan, incorporate Symmetry
into an overall Cut grade.
