Learn about Symmetry Symmetry is an important
element of diamond finish. Symmetry refers to the exactness of the shape
and arrangement of facets. This includes naturals, misshapen facets
and extra facets, off center culets and tables, wavy and out of round
girdles, misalignment of crown and pavilion facets. To the unaided eye,
finish features usually have little effect on appearance; they are like
pinpoint inclusions. The importance of symmetry is less important in
diamonds that have lower clarity grades. Symmetry is more important
in diamonds that have very high clarity grades.
When selecting your diamond, choose a diamond that with Excellent, Very Good or Good Symmetry as listed on the diamond grading report. Diamonds with fair to extremely
poor symmetry should be avoided. Listed below is a list of abbreviations
and brief discriptions of symmetry grades that are used by GIA, EGL,
and IGI. EX or E - Excellent,
Flawless at 10 power Abbreviations vary slightly
due to variables in database input.
