Would an ASET reveal something that I am missing?

I was reading another thread on here that posed the question of whether an AGS certificate that doesn't have an ASET included means that something about the stone is possibly being hidden. So I got to wondering whether an ASET image can reveal something that an idealscope image will not.

From what I have gathered, an ASET image will more or less show you where the diamond is gathering the light from that it returns back to the viewers eyes. Whereas an ideal scope simply shows the amount of light returned? Is that the idea or am I off there?

Others then suggested that if a stone has an AGS cert without an ASET it may mean that the vendor did not feel it would have good patterning and therefore did not request a certificate with an ASET image.

The diamond I recently purchased is AGS certified but does not have an ASET image, so now I am asking myself if that means I am missing something? The AGS report can be found here: http://www.agslab.com/reportTypes/pdqdf.php?StoneID=104068958003&Weight=1.79&D=1

Here is the diamond link: http://www.jamesallen.com/loose-diamonds/round-cut/1.79-carat-i-color-vs1-clarity-sku-280487

Here is the idealscope image of the diamond: 280487.jpg

And here is a picture I took and cropped through a hearts and arrows viewer: hna.jpg

The decent hearts make me think that the patterning would be pretty decent on an ASET, at least from the pavillion view. I don't have an image of the arrows.

I will admit, I was trying to find the best bang for my buck without having to buy a branded diamond. But now I question whether I should have just paid the extra money for an ACA and saved myself the agony of questioning whether I had done a good job in selecting a great stone. I paid 14k for this stone and if I had wanted an ACA I would have paid at least $400 more for about 0.10 carats less in weight.

Am I worrying needlessly or do you think an ASET might show something about this stone that I don't know about?
 
Based on the IS, an ASET would not reveal anything of interest.

In this case - probably not. However, I’d want to see the ASET personally in *every* case. Why? Because, thanks to separating where light is drawn into more areas, ASET can reveal things that the IS may not. Any time the diamond has aberrations IS may not reveal (especially with regard to areas of painting or digging on a RB) the ASET can show this where it may not show on an IS image.
 
Nice Stone. Ideal scope looks good.

I believe it was my thread asking the questions re AGS0 and possible light return issues on non platinum certs. Your IS doesn't show anything to be concerned about, but you wouldn't expect them not to either based on the dimensions. With my thread I'd read a few people suggest that 35/40.9 is towards the threshold for steep deep which is kind of why I alluded to possible issues with leakage on the AGS0 outliers.
