I bet they would not be obvious on the hand.  I am willing to try and find them.   Send it to me David and I will take the challenge. 

I actually did a test similar to this to put into perspective a slight feather near the edge of a radiant cut stone that was graded SI1.  With the 50-100x magnification of the stone in photos, my girlfriend and I couldn't move past one tiny piece-of-paper that was mostly visible from the back of the diamond and only noticeable from certain angles at the magnified sizes.  As we spoke, I had to stop us and put it into perspective.  I cracked open photoshop and set my canvas size to plain letter.  I then zoomed into 2500% to draw the exact measurements of the diamond (it was a radiant in the roughly 5x5 mm range, a bit under a carat in total weight).  I then marked a small path near the corner looking at the GIA plot of the diamond to match the feather as best I could by eye.

Print and squint!

If you're like me and using a 24" flat panel, then you're bound to find some of the photos of diamonds on DBL are very close to the size of a sheet of plain letter.  Mark out the dimensions with a ruler or photoshop up a life-size comparison and you will be amazed.  Points like the pepper are a fraction of a fraction of a millimeter.  [Although I did gasp when I saw the plot and photos!]

I agree, it is a worthless stone.  Should have been graded I2 with all of those inclusions.  It might be salvagable as a pendant.  Send it over and I will see what I can do.
