Flourescence

[hfc]

Does anybody know if slight to medium flourescence make a diamond look whiter? I've recently seen a H colour diamond that look as white as one that is graded F colour.

That's true.

:

"Blue fluorescence can be an advantage, particularly in lower (below I) colored diamonds, because blue is the complimentary color to yellow. Adding blue compensates for yellow and makes the diamond appear whiter in any light that has an ultra violet component (e.g. daylight and halogen lighting)." [/u]
