is this a type of AGS cut analysis?

[jerichosmom]

I've seen a few of these listed for loose stones. There's no AGS report number for reference and none of the offered products on the AGS website look like this. This stone is being advertised as "near-ideal" as it's .02mm too deep and missed the mark. The stone is in Canada if that helps (perhaps AGS Canada has different reports?)

Thanks for your input.

Not sure where they are getting the ags0 unless it is the old proportion based score some sarin machines output.
That diamond is not likely to get 0 under the new system it would likely get a 1.

That's a report from a Sarine machine that's used to measure the various angles and such on a diamond. They're estimating what they think AGS would have called it back before AGS changed their rules in 2005. This is definitely NOT an AGS report, even from that time.

The 64.3% depth would drop it to GIA VG and AGS 3, regardless of optics. That means a 1.00ct diamond with those proportions only has the face-up spread of a well-cut 0.90ct...a smaller resultant look than the carat weight might indicate. If the price has been adjusted to reflect that, no problem, but it's something to be aware-of.

As Karl implied, those 2D proportions are predicted for AGS 1-2. The actual performance score would depend on many details involving minor facet choices, variation of actual facet measurements from average, cut consistency and brillianteering.
