There seems to be some debate about fluorescence in colorless and near colorless diamonds. Some in this subgroup say that SB and VSB usually cause danger in diamonds with higher color grades, while others say this is usually not the case and for the vast majority of time it does not cause the diamond to look cloudy, greasy or cloudy out. I found this YouTube video comparing a VSB and no diamond (both G color) in direct sunlight. [https://www.youtube.com/watch?v=9DwpO-w-qXE](Https://www.youtube.com/watch?v=9DwpO-w-qXE)
The diamonds certainly look different, but I wouldn’t say VSB looks cloudy, cloudy or greasy. Is that what you mean when you say hazy? Because I think it has its own charm, different, but not necessarily less appealing.
