Diamond Symmetry
Symmetry refers to how precisely the various facets of a diamond align and intersect. This can include extra or
misshapen facets, off center culets and tables, and wavy girdles. Sometimes, a diamond cutter will deliberately
allow a minor reduction in symmetry as a way of preventing a defect present in the rough stone. Symmetry typically
ranges from 'Poor' to 'Excellent'.
Symmetry has a limited impact on the appearance of a diamond, and a greater impact on price. A diamond with
'Excellent' symmetry and Polish may be priced higher than a diamond with 'Good', 'Fair' or 'Poor' because they are
perceived as more valuable and the lower symmetry grades will have a higher probability of noticeable defects.
Each Anjolee Diamond™ Certificate displays the symmetry grade, using the following scale:
| Excellent |
No symmetry defects visible under 10x magnification. |
Anjolee Diamonds |
| Very Good |
Any defects are very difficult to see under 10x magnification. |
Anjolee Diamonds |
| Good |
Any defects are difficult to see under 10x magnification. |
Not carried by Anjolee |
| Fair |
Defects are noticeable at 10x magnification, and may be visible to the unaided eye. |
Not carried by Anjolee |
| Poor |
Defects are visible to the unaided eye. |
