why should it follow a statistical pattern?
cutters are very confident in what grade the stone will get before it is submitted. and virtually all stones will be a 0 or 1, as anything else will not get a cut grade.
You'd have to look at all the AGS stones that were EX/EX with proportions that are 0 candidates. I find most of the AGS stones without cut grade to generally be poorly proportioned. There's no way to sort for BN's AGS stones, so it's conjecture.Date: 2/10/2009 8:59:41 PM

Good answer...but I think for the wrong reason.
Yes, it might follow a pattern...if all cutters were required to send all stones there. But...they're not. So, to begin with, they have to think they'd have earned a 0 or 1 to even send it in.
But...they might be wrong in their guess. What's the result? Go to Blue Nile, and sort by AGS. But...you'll see a good number without cut data. Probably, they didn't get the zero, and decided to hold & fold...and just get a reporting of the data, and call it a day.
But...check me on this.
Sure you can...just select on the column.Date: 2/10/2009 9:45:10 PM

You likely wouldn't do it on 100% of their offerings. But for any given sort...you can gather together the sample there and look at each AGS option.
But what are you otherwise saying? Most AGS stones without cut grade are generally poorly proportioned. What rationale, then, must be used to send it to AGS. This is a real question. They're actually being sent there to avoid getting a cut grade? Wouldn't it be better to send to EGL for being called ideal, regardless of the proportions?

These are all interesting answers....I asked because I just bought an AGS0 cut and when I describe it to people they have no clue what I''m talking about. I was trying to find a way to re-frame the description by saying the top (insert percentage here) of all cuts.
But this seems like I''ve asked a loaded question with no set answer.
GIA is Ivy League, and AGS is like the MIT rocket-science program.
A polisher or manufacturer sends each diamond (student) to the place it will get the best grade (earn more $).
The good to average go to the large universities (IGI/EGL).
EGL stones are harder to sell, I assume. GIA has a long turnaround time. (And maybe GIA is more expensive?) Even, it might not get GIA EX.Date: 2/10/2009 11:08:30 PM
