Refers to variations in a diamond’s symmetry. The small variations can include misalignment of facets or facets that fail to point correctly to the girdle. Symmetry is regarded as an indicator of the quality of as diamond’s cut; it is graded as either Ideal, Excellent, Very Good, Good, Fair or Poor. There is always the possibility that the girdle may not be perfectly round, facets maybe distorted, sloping table or points not symmetrical, though these have not much of an impact to the diamond’s appearance, a terrible misalignment can diminish the reflection and hence its brilliance.

Tips: For fancy looking diamonds, a grade of good is preferred, while for a round shape diamond, a very good grading and above is preferred.
