I found a ring on the internet that has these classifications-- Color F, VS2, GIA, Ideal cut, Girdle is thin-medium faceted, culet-none, polish and symmetry are "good", and the flourescence is "strong". I know what all the others mean, but I''m still not sure if strong flourescence is good or not. Also, if the rating of "good" under polish and symmetry OK? Any input would be appreciated. Thanks!
