Hello All,

After doing a decent amount of research, I've been able to figure out how to tell whether an Idealscope or ASET image is acceptable, but I'm having a harder time determining which images are better from within the category of acceptable images.

Hopefully, you guys can provide some feedback regarding the performance of a couple of diamonds that I'm considering purchasing. Where in the range of performance do these stones appear to rank (are they elite performers within the EX cut category, or are they merely on par with most EX cuts?), and which of these options has better light performance based on the following images? Thanks in advance for your help! Both diamonds are GIA XXX and have HCA scores below 2.

Diamond #1:

or...

Diamond #2:

I am going to go with diamond number... 2
 
That's what I thought. Based on the above images, can anyone tell me how diamond #2 compares to the best cut, H&A-branded stones? Basically, does diamond #2 look like an elite-performing diamond?
 
A note about the photographic setups you're comparing:

The first Ideal-Scope image has brighter backlighting, so it's a bit harsher, but the second is backlit very appropriately. The environments are close enough to be compared head-to-head.

The ASET images are from different setups. The first ASET was backlit. The second was not. Backlighting is always harsher and reveals more than non-backlit.

The above is intended as education about recognizing backlit versus non-backlit setups. In my opinion, both of those diamonds exceed 95%.- of diamonds in commercial markets in terms of cut-quality.

You shouldn't crack your knuckles, you'll give yourself arthritis later in life.....

Great points John, thank you! Good to know also your opinion as a pro how these two would rank with more mainstream stones.

Thanks for the information about the back-lighting. I was wondering why the first set of images looked different than most of the images provided by retailers. Also, thanks for your opinion regarding the cut quality.
 
I don't know if the first is eye clean but this would put it in the exclude category.

Not including the clarity, I certainly wouldn't immediately choose the BG select over the other one based on those images. In fact the pavilion mains of the other seem to have better consistency of width than the BG and may in fact have better optical symmetry. Whether this translates into something noticeable Is another story and any performance differences are likely a function of other criteria in this case that can't be immediately spotted in these images. But I don't think the BG select is the clear winner here based on the images.
