I know that its of little consquence and probably not noticable. In fact I have earrings with only very good symmetry or polish (i cant remember which) and it doesn't bother me for earrings. It did a little in the beginning but I got over it because they are just earrings. But for an engagement ring I would want something triple excellent. If just for my neurotic psychopathic and completely unreasonable peace of mind! Lol
just so you know--no one will know but you. you couldnt pick it apart from a very good. its not probably not noticeable --it is not noticeable. most people dont really understand polish and how it is graded.
