A client brings a diamond with a fluorescence grade of 'Strong Blue.' How might this affect the appraised value of a D color stone?
-
A
It always increases value because blue complements colorlessness
-
B
It may decrease value because strong fluorescence can cause a hazy appearance in some D color stones
-
C
It has no effect; fluorescence is not a valuation factor
-
D
It increases value only if the diamond is over 2 carats
