Fluorescence in diamonds

[shannoncaw]

Hi I have a question regarding florescence. I've read that a diamond can appear cloudy or milky in sunlight with a diamond that has a strong florescence. The particular diamond I am looking at has the following GIA report
Report GIA
Report No.
Shape Round
Weight 1.00
Measurements 6.34x6.42x4.00
Proportions
Depth 62.7
Table 55
Girdle THN-STK
Culet NON
Finish
Polish VG
Symmetry VG
Clarity Grade VS1
Color Grade J
Fluorescene STG
My question is since this is an internet purchase and I can not see the actual diamond is it posible the diamond could be cloudy with a clarity grading of VS1.

Sounds like a benefit rather than a concern.
But as always - get an indeependant apraiser to eyeball it for you!!!!
