There is some degree of subjectivity, is there not? Because to my eyes, using only Leibish's photos, this diamond appears to be dark enough in tone to be classified deep. I suppose under the standardized GIA lighting, it may look completely different.
That is a very handy chart, Kenny. I have spent quite a while trying to visualize the difference between saturation and tone and have struggled - it seems to come very easily to a few other key members of the CS board. Seeing the diamonds lined up in progressive degrees of both saturation and tone make it a bit clearer. But I think when comparing to two stones, side by side, I would still struggle to describe whether one had darker tone or deeper saturation.

I suppose it just takes practice. Thank you for all your help, Kenny.
And - as for this diamond - do you see red in it? In the second, horizontal picture, on my screen and to my eyes, it is fairly reddish pink.
Ideally we would all have access to a wall chart comprised of 1,000,000 real live pink FCDs meticulously arranged by GIA into their categories, and then positioned carefully
within their categories.
This wall chart would be perfectly, evenly and shawdowlesly illuminated.
Next we'd have the actual FCD we are considering purchasing to hold up to the huge wall chart.
Baring that ideal world we are stuck with all the limitations of photography, computer monitors, faded printed GIA reference charts and yes, human subjectivity and even the possibility of human error.
Next throw in the customer's personal preferences and bias.
I'm just glad that Leibish has a good return policy.
FCD shopping is a real pain in the butt.
I have a "pure" vivid yellow per GIA and there is NO way that baby is pure yellow.
When GIA assigns a hue, again it is a
range that is centered around one point of pure yellow - the entire Vivid Yellow grade is not a point hue-wise.
GIA pure yellows can vary; one one side of the range they can have a little green, brown on another side and orange on another side.
I think it is the same way with GIA's Deep grade in terms of tone.
I suspect this is very near the border of deep and that may explain the attractive price for a GIA Fancy Intense.
I do see some reddish in it but that means as much as you read into it.
GIA did not put the word red on the report.
