The GIA cert says “medium” for the fluo?? I was under the (possibly mistaken) impression that it was usually “very strong” or “strong” that were likely to cause issues? Hopefully someone expert will explain!
'Usually' it's said to be strong or very strong blue fluorescence that can cause haziness/ milkiness and only rarely at that, the diamond in this case is medium for fluorescence if I'm correct? So in which case, I wouldn't think it's an issue, any visible haziness I would want clarification on...
Also opinions differ whether medium, strong or VSB has any beneficial effect on the colour grade, some think it does, others not so much.
