The fluorescence size for diamonds ranges from "n1" to "very robust," with grades in between including faint, medium, and robust. However, whether or not fluorescence is "higher" depends on non-public desire and the particular diamond. In a few instances, faint to medium fluorescence could make a diamond seem whiter, in particular in decrease Color grades. but, strong fluorescence might also from time to time reason a hazy or milky appearance, especially in diamonds with better colour grades.
