This is the GIA paper quote: Tradespeople further observed that some gem diamonds with a hazy appearance also fluoresced strong blue to UV radiation. (Paper here)
The paper is careful not to assign causation - or even definitive correlation - to strong blue fluor and the haziness/oiliness often associated as a potential problem with stones w/ strong fluor.
So - if there is a causal relationship here as is commonly suggested here on PS and in conversations with jewellers, if strong blue fluor is responsible for the haziness/oiliness, can one of our tradespeople or experts help me understand why? What property(s) of the emissions/the nitrogen substitutions are to blame?
Or is it just a happenstance characteristic of a diamond that has certain other properties?
I'd really appreciate anyone pointing me in the right direction on this.
ETA: Posted in RT b/c it's a question I think many buyers may have when warned of the possibility of problems with stones w/ strong blue fluor
