http://www.jamesallen.com/diamonds/H-VS2-Ideal-Cut-Round-Diamond-1225114.asp?b=16&a=12&c=77&cid=131

How often do VS2''s have carbon in them? I know the whole thing is carbon, but the black carbon I mean.

TIA
The only way to tell is to ask the vendor to evaluate it for you abe, otherwise we are just speculating, you can''t go by images with this sort of thing regrettably.
 
I know of an AGS VVS1 Whiteflash ACA with a carbon spot.

Just one very itsy bitsy one near the girdle, but it is a black carbon spot.
 
Is that still eye clean?
 
This VVS1 is absolutely eye clean.

Generally 99% of the time GIA and AGS VS2s and above are always eye-clean.

This tiny carbon spot is very very hard to find with a loupe and is the only imperfection in this VVS1.

It is around SI1 where eye-clean becomes more squishy.

VVS1 is always eye clean.
 
I was unable to get the zoom option on the lab report feature to "zoom" but it looks to me like the diamond crystals indicated under the plotting diagram and the cloud (of pinpoint size diamond crystals) is located within the table section of the diamond and not in the lower left quadrant. I took the loupe tool for a spin and did not see anything in the lower left quadrant of the diamond that looks like a diamond crystal type of inclusion, but you should confirm this with James Allen. Here''s a screen shot of the inclusions which I believe to be the primary grade makers (I couldn''t see the feather on the report or via the loupe tool). Note that the diamond crystals in the center of the table area appear dark through the loupe tool, but they may actually be translucent - inclusions such as these often appear dark in clarity photographs because the image is taken while back lighting the stone and it causes the subject between the light source and the camera to appear dark unless it is offset by another light source - Photography 101 and all that.
