EDIT: Sorry, I see the specs on page 1

Frisbeenut, let me start by saying that your ring is quite beautiful.
I am also a diamond newbie, but I work with fluorescence in scientific research. In my opinion, if the blue that you're capturing in these photos is fluorescence, you should be seeing a lot of blue in the pavilion in the sideways view. As you know, stones are viewed sideways to evaluate color, because from that angle, there are no reflections to obscure what is truly happening inside the diamond. In the same way, a sideways look into the pavilion should give you the best possible view of any emitted fluorescence (which come from inside the diamond, and generates light that radiates in all directions, including back towards the viewer). What I'm getting at is that if the fluorescence generated by your diamond under sunlight was as strong as your first image suggests, we should also see a deep blue pavilion in that last image.
This is not a critique of your diamond in any way, in fact the large amount of blue coming off the diamond is a direct testament to its extraordinary light return properties (but IMO, due almost entirely to reflections of the blue sky).
Thank you for your great reply. I really had not spent a lot of time with the ring (it's now on my fiancées hand and she currently does not live with me...this will change in 2 months...but I have been thinking the same thing the more I analyze the photos (like many here even though I have purchased the ring and she and I are very happy with it, I can't help but keep reading these forums!). But I think you are absolutely right, the side view is the truer representation of the blue fluorescence...it actually looks more purple than blue especially in the photos. The deep blue in the top down view I do think comes from the light return from the pavilion mains and that it is a bit misleading the top down view. I did comment initially that I thought that part of the blue was from the sky reflection but now I am more in your camp and think the majority of the blue is from the sky reflection with the fluorescence contributing the minor portion. I really do want my photos to give people here on PS a good and fair representation of what a strong blue Fluor looks like and that one should not immediately fear the descriptor as in reality it may not negatively affect the beauty of the diamond at all. As many people have commented and linked to the 1997 GIA fluorescence study, one is very unlikely to find the hazy blue phenomenon due to fluorescence than not. In fact I went ahead with this diamond based in part on the nature of the defects that were outlined in the GIA grading report, as others have mentioned and I tend agree with them (though based on no hard data only general insight) that twinning and cloud defects if very prevalent may contribute to haziness under fluorescence due to internal scattering of the fluorescence light by those defects. I think of it like seeing a beam of sunlight due to scatter off of dust particles in the air, though I have not really given a lot of thought to whether the size scales of cloud and twinning defects in a diamond would be similar to say dust. With that said as with any diamond, you need to see it in person the make the call.
Really appreciate the comment and feedback.
I only bring this up because, as you noted in your original post, there is a lot of confusion about fluorescence-- even on PS. I've seen several new diamond owners here who have purchased a non-fluorescent diamond (because that's what they wanted), and who became worried and concerned because their diamonds looked blue under a blue sky. I even saw someone who ended up returning a beautifully cut, bright diamond (which reflected a ton of blue sky on a sunny day), for what seemed to me to be a worse-performing diamond that was not returning any blue-sky light on sunny days.
So I'm hoping that some experts will either confirm my suspicions, or correct me if I'm wrong. There is too much misinformation out there about fluorescence, and it can sometimes have sad consequences.
Thank you. She thinks so too!TruLuv858|1409354521|3741742 said:Your ring is just stunning!! Its soooo sparkly! Alright, I have to go clean my ring now
Than you!Calliecake|1409364944|3741816 said:Beautiful ring. It looks so pretty on her hand!
Polished|1409370870|3741876 said:A simply gorgeous ring. This thread has also expanded my knowledge of Flourescence. I have a D coloured diamond with no fluorescence but in the sun it can turn blue. It had me wondering but I think it may be that it's a very white diamond to begin with which might mean that it reflects the blue (very blue skies here in Australia) from the sky even more.
