it can't possibly... unless it's horribly asymmetric! If the ISs/still photos have too much black I'd guess they shoved it way too far into the scope or held the camera too close, I've taken some awful close-ups with my (black) P&S of what I know is a perfectly fine stone, by forcing over-obstruction by just getting in too close
No IS images, the pictures are like the type we all take here on PS of our diamonds. Some look like it has obstruction or a black area in the middle, but as you all say, I have taken some poopy photos of my stone so I guess that is it!
