Does anyone have any photos of D-J (or similar range) diamonds taken, face-up under controled conditions? By controlled I mean with the processed image profiled to the camera / light colour temperature (with say a Gretag chart)?

Here are two from an old thread titled "Diamond color chart" the second one has some face up comparisons. In case you hadn't seen them, here they are.

Thanks.

SuzyQZ - that second one was pretty much what I was looking for, thanks. Looks like whoever took it at least corrected for light color temperature - hard to tell on saturation and gamma.

GarryH - seen that chart before when you answered one on my Qs on yellow stones
. It''s really interesting, do you know what the shape is third from the right?

I''m going to guess a Gabrielle Tolk flower cut
