Question about very light fluorescence

[Cricketcat]

I am purchasing a WhiteFlash Expert Selection diamond. It is a J color, 1.33, and was graded by AGS. Everything looks very good to me about this diamond. WhiteFlash told me the reason it missed the ACA category was because one of the heart shapes was not to the ACA standard. Over the weekend I read up a bit on fluorescence. GIA and AGS grade fluorescence a little differently. GIA can grade a diamond as having "none" or "faint". AGS combines none and faint into one category of "negligible". The only question I hadn't asked about this diamond, I did today. I wanted to make sure of the diamond's fluorescence as the diamond I have picked out is graded as negligible. Whiteflash told me their gemological team noted it has very light fluorescence, but is so insignificant that it got the AGS grade of negligible. Do I need to worry about this 'very light fluorescence' level? Is the diamond going to glow in the dark or turn blue outside? I was reading on Brian Gavin's website that the requirement they have for their signature collection is a fluorescence rating of negligible to faint blue. (Made me feel better). Should I be ultra picky about the very light fluorescence and look for a diamond that really has 'none'? Really want to get pricescoper opinions on this. Thanks.

Nothing to worry about a "negligible" stone..
