Help evaluating this ASET image

[emb2519]

Hello, this is an ASET image taken by a vendor for a diamond I'm considering. I'm not comfortable with what to look for, and would really appreciate your help.

Thank you!

my concern is that the main facets are black, shouldn't they be blue?

That may be an issue of exposure or white balance, not an ASET problem. I'm no expert, but I've read here the exact color or intensity don't matter so long as the color (either blue, red, green, or white [leakage]) in general shows up. I don't see any considerable leakage and there's lots of red, so I say it looks good!

It looks like a nice stone. The black/blue issue doesnt matter.

We usually request idealscope images for rounds (instead of asets). Please post if you have one.

Ditto the stone looks fine.

Blue/black can be hard to differentiate in backlit ASETs but it does look vaguely blue, and more importantly the patterning is consistent with contrasting mains (it'd be an awfully bizarrely configured stone for the mains to leak before the steeper lower girdle facets!)

That's about the photograph, not about the diamond. Taking good ASET photos is actually remarkably difficult and sellers approach it differently. Talk to the dealer about it but I don't think the blue/black thing is likely to be evidence of any sort of problem.
