Symmetry is analyzed using a 10X loupe magnification, by trained professionals. Renowned gemological laboratories like the GIA and AGS follow stringent standards to judge the diamond symmetry. Every diamond graded by the GIA comes with a symmetry grade report. Diamonds are graded Excellent, Very Good, Good, Fair, Poor, Very Poor or Extremely Poor depending on the cut quality. Diamonds with Excellent or Very Good symmetry are rare and difficult to come across. The diamond with ‘Good’ symmetry grade is brilliant, readily available and more popular with diamond lovers. Grades below Fair display poor brilliance, not impressive in jewelry.
These are the abbreviations used by the GIA and other prominent diamond grading organization to describe symmetry.
