Confused about Flouresnce

[ma1lyc]

So after months and months of research here, I thought I knew enough to be a smart shopper from my diamond. I liked the look of flourescence, so when picking my stone i made sure that it had flouresence in it. My stone has a strong blue flour. which at frist I thought was too much. but double checked with the vendor that their was no hazy and milky effect. Anywhoo, i brought the diamond to my jewelers to set my stone, this jeweler is seems to know what he''s talking about unlike other sales rep. We were able to converse about diamonds/ specs etc... and he knew what i was talking about exactly from everything i learned on pricescope, and more. Well he was the owner of the jeweler, so being more knowledgable than the average sales rep is expected. The one main thing that we disagreed on was FLOURescence, he disagreed that a flour at on a high color diamond (mine is E) is Bad, and causes 99% neg affect, and affects the brillance of the diamond. He asked if i knew that before purchasing a diamond of stong BLue on a E color diamond. I told him I did alot of research on my diamond, and have learned that ON high color diamonds there is a greater chance of neg affect, but not likely. I told him that i had it checked out from my vendor if there were any neg affect before purchasing it and there was not. But he still disagreed with me on the Flour. Now im doubting my self for buying a FLour diamond. My diamond is sparkly, but now i''m wondering if it could have been more without the Flour. Why would a knowledgable jeweler disagree with what is said on Pricescope. I don''t think he was trying to get me to buy one of diamond instead, considering i already had one and was being dropped off to be set by him.

Don''t listen to him. It''s all about what YOU like and if you love your flour, that''s all that matters really.

It won''t help the color like it would if your diamond was say a J, but as long as it''s not hazy, it''s fine!

You can ask him to find you a similar stone without a flour and compare yourself, well if he can.

He holds a common old-school trade notion, disavowed in 1997 by this GIA study.

Excerpt: "In the table-up position (as is commonly encountered in jewelry), diamonds described as strongly or very strongly fluorescent were, on average, reported as having a better color appearance than less fluorescent stones. In this study, blue fluorescence was found to have even less effect on transparency. These observations confirm GIA GTL’s experience grading millions of diamonds over the decades... ...The present study also challenges the trade perception that fluorescence usually has a negative effect on better-color diamonds. Our results show that the diamond industry would be better served by considering each individual diamond on its own visual merits."

The last sentence is sage advice.

Flour is very rarely a problem even in higher color stones, and if there was a problem you would easily be able to detect it. Enjoy your stone!!!

I would not worry about. Examine your stone in a variety of lights. See if it changes in any way that is bad to your eyes. I have seen different stones all rated as "strong blue" do vastly different things, so there can be a variety.

But I do disagree with your jeweler. He is just relating an old stereotype.

I really like fluoresence after studying it for some time. I have a D w/ strong blue - it''s awesome!
