Polish can be result of the finishing process or be affected by blemishes created after
cutting. The term "Polish" refers to the degree of "polishing lines" that appear on the
surface of a finished diamond which can be seen with the use of 10x magnification. These
polishing lines are caused by the minute diamond crystals which are embedded in the polishing
wheels used by the diamond cutters to polish the surface of the diamond after cutting. While
not quite the same in appearance, they are similar in concept to the swirl marks left on the
surface of a car from the use of an orbital buffer, but are much less noticeable.
It is important to note, however, that polish lines are straight in appearance.
|Code - polish
||This is our predilection. No polish lines or marks are visible when the diamond is viewed under 10x magnification. High magnification, such as 30x may be used to locate any possible imperfections. The brilliance of a diamond with Ideal Polish will be noticeably superior to that of a diamond with a polish rating of Excellent.
||This is our preference. No polish lines or marks are visible when the diamond is viewed under 10x magnification. High magnification, such as 30x may be used to locate any possible imperfections. The brilliance of a diamond with Excellent Polish will be noticeably superior to that of a diamond with a polish rating of Very Good.
|(VG) VERY GOOD
||Represents diamonds that contain one or two minor groupings of transparent polish lines that are visible under 10x magnification. Higher magnification will again be used to locate these areas easily. The degree of brilliance between a diamond graded as Very Good in Polish and Good is still noticeably different.
||Numerous areas consisting of minor transparent lines are visible under 10x magnification. Occasional white polish lines may also be visible, but limited in number. As a bare minimum, we recommend that a diamond have a Polish Grade of Good or better. However, it is important to note that it is difficult to have Excellent or Very good polish in most of fancy shape diamonds so generally it carries Good polish.
