As the stone 'just' made the 2.00 Ct mark (cutter would be pleased ... 2.00 = profit > 1.99) ... one wonders if there was some compromises made there to retain carat weight.
Absolutely. The rough was shaped so that the girdle had to remain 'thick' in places in order to recover 2.0 carats. Still great proportions though. It was a small compromise, but sharp analysts will take note.
The clouds and the surface graining mentioned in the GIA report may have a negative effect on the stone's overall 'cut grade' - who knows? One of the experts may have a comment. Still, a VS2 should be relatively eye-clean and the inclusions have a minimal (if any) effect. I haven't had a look at the 40x magnification photo.
ASET and IS appear 'perfect' so there is every chance this stone - if you can afford it - is a good buy.
No worries on the clouds or graining. Many times a diamond grading report will list surface graining, pinpoints, additional clouds, etc. as 'not shown.' The diamond's report is just noting that these things exist for sake of thoroughness. 'Not shown' means they are non-issues (an exception is an SI2 diamond where clouds set the grade).
Surface Graining is diamond structural irregularity. You can see it with a microscope. The diamond graining may resemble faint facet junction lines, or cause a grooved or wavy surface. They look like polishing lines, but they often cross facet junctions where polishing lines don't. It is a natural characteristic of the diamond crystal, and not a reflection of the diamond's cut quality. Additional Clouds are mentioned, since they were taken into consideration for the diamond's total clarity grade. Not drawing them is standard procedure and nothing to worry about.
Good discussion.
