Diamond Symmetry


Diamond symmetry is determined by the way a Diamond is cut and both facets and proportions are assessed to help determine a symmetry grade for most certified Diamonds. 

Excellent Symmetry

Ranges from no symmetry features to minute symmetry features that can be viewed with difficulty face-up at 10 x magnification.


Very Good

Minor symmetry features are seen face up at 10 x magnification.


Good

Noticeable symmetry features are seen face-up at 10 x magnification. The Diamond’s overall appearance may be affected when viewed with the unaided eye.


Fair

Obvious symmetry features are seen face-up at 10 x magnification. The Diamond’s overall appearance is often affected when viewed with the unaided eye.


Poor

Prominent symmetry features are seen face-up at 10 x magnification. The Diamond’s overall appearance is significantly affected when viewed with the un aided eye.
