Whether diamond with this feather inclusion is eye clean?

[karsa]

I ran across this diamond and I'd like your opinion as to how visible this feather inclusion would be with the naked eye as well as with a loupe (10x mag). The feather is very tiny and faded white in color and it is slightly visible underneath the table on one of the arrows (due to head obstuction) as the diamond is revolving around.

Re: Whether diamond with this feather inclusion is eye clean

What is your definition of "visible w/ naked eye"? Does it match JA's definition of eye clean (diamond that is clean face-up from 8-10"), or do you want it to be clean at significant tilt from face-up, clean from the sides, clean from 4", etc.?

Since none of us have the stone in-hand and we have neither your vision nor your personal requirements we can only really talk about generalities, but... *in general* a VS2 of this size is going to be clean (by unaided inspection) to most people's requirements. Because, well, most people's requirements can be summed up by 'clean face-up from 8-10"'

Inclusions are listed on the report in order of most to least "severe" under 10x (per GIA's grading spec), so the cloud(s) is the grade-making inclusion in this stone. This stone only has the GIA dossier, but David of DBL calls the GIA plot diagrams for larger stones inclusions roadmaps and it's an excellent analogy - the plots don't tell you anything about actual visibility of the inclusions IRL, just where they are and which one(s) the graders deemed most "severe" under magnification.

Clarity grading is by far the most opaque (to the consumer) of the 4 Cs, IMO. Here's a thread that asks some of those questions - and, again IMO, answers them with yet more questions! But it's illustrative, and hopefully illuminating nonetheless.

To be perfectly honest... for the vast majority of consumers I would say that this stone was a perfectly promising option, and the fact that you're questioning whether it's clean to your standards at all indicates that you'd really best see it yourself to judge! I see what you're referring to re. white inclusions standing out over the obstructed mains, but I'm on a tablet and it's way too small to guess which are clouds/feathers... but IRL the mains aren't going to be obstructed like that unless you're leaning over it face-up, and that's a relatively rare occurrence. Assuming they are in fact visible to naked eye IRL, which I'm not at all confident is the case, you can be sure that from all other views they'll just blend in with the rest of the white/silvery faceting. My suggestion would be to first ask JA if the stone is clean to your requirements, whatever they are, and then have it shipped out loose to inspect and confirm that you're happy with it.

Thank you for your input
As a matter of fact, when i mean visibly eye clean, i mean if i were to rotate this diamond in various tilt angles 360 degrees, just the way JA video shows, i would not be able to see even the slightest hint of a feather by just looking at it from 3 inches away as well as if i were to use a loupe that i would only see an extremely miniscule faded white pinpoint in the diamond as i rotate it around in various angles.

i made the image smaller and i was still able to see a hint of a faded white short line segment especially since i knew what i was looking for. Yes, in terms of proportions wise and idealscope image, it is a very promising stone but the little feather makes me anxious.

I have asked JA and they said it was eye clean, but i am not quite certain if that is truly the case.

Probably the feather would blend in with the rest of the background but not 100% certain. Since i am in toronto i would rather be sure first since shipping cost is expensive.
