Diamond Polish And Symmetry Grades
Diamond Polish And Symmetry Grades. The diamond is examined by gemologists at 10x magnification when determining the polish grade. For instance, a diamond which has a “very good” symmetry might still get an overall cut grade of ‘excellent’ if the other parameters are up to the expected mark.
The clarity of the facets and cuts of a diamond are dependent almost entirely to its symmetry. When determining a diamond’s polish grade, gemologists will look for the presence and visibility of certain features at 10x magnification. Symmetry refers to how precisely the “point” of each “facet” is aligned with the “point” of the adjacent “facet”.
Again, Similar To Diamond Polish, A Grade Of “Poor” Means The Facet Alignment Is So Inferior It Has Impaired The Diamond’s Appearance.
The grades are based on the visibility of polish lines or other blemishes on the skin or surfaces of the diamond. Moreover, symmetry involves the angles and lines that form the placement of the facets. For example, let’s say you have two diamonds side by side, and each are 1.5 carats, vvs2 clarity, an f color, and have excellent cuts.
This Means That A Diamond Can Have A Variance Up To 0.06Mm.
As with diamond cut, color, and clarity, diamond symmetry and polish are graded on a diamond’s gia grading report. One must realize that with regard to polish and/or symmetry, there are many facets and “points” of a diamond. Every round gia certified diamond, like the round cut diamonds pictured above, will receive its own symmetry and polish grades.
· Diamond Polish And Symmetry In Case Of Colored Diamonds Are More Flexible.
As a bare minimum, we recommend that a diamond have a polish grade of good or better. One diamond has excellent symmetry and polish and the other is graded “very good.”. The diamond is examined by gemologists at 10x magnification when determining the polish grade.
For Instance, A Diamond Which Has A “Very Good” Symmetry Might Still Get An Overall Cut Grade Of ‘Excellent’ If The Other Parameters Are Up To The Expected Mark.
Nowadays, symmetry is completely controlled by. Hence buying diamonds with a very good polish is a nice cost saving option while keeping cut (proportions) and symmetry excellent. Anatomy of a polished diamond (facet nomenclature).
On The Other Hand, The Diamond With A “Good” Symmetry May.
These diamonds are cut to maximize the brilliance and sparkle of the stone. This way the premium price tag of the triple excellent. A diamond’s symmetry is how well.
