should i be suspicious of this?

[atropis88]

i have this stone on reserve but after a close 2nd look i'm becoming a little skeptical about it. it's WF ACA which i'm assuming means is absolutely superb. it's .8 I SI1 and supposedly eye-clean. I just don't know what to make of the huge cloud right smack in the middle, and I think it has impacted some of the light performance based on a little green blotch between 2 and 3 oclock. Should I not be worried about this? I've also read that light performance measurement machines can potentially not detect light leakage that may be caused by an inclusion. Any thoughts would be highly appreciated.

i would double check how they classify 'eyeclean' its a subjective thing. it usually means to normal eyesight at a normal viewing distance. which is pretty variable. it may well be eyeclean at a normal viewing distance, but it might not hold up under close inspection. that cloud is very big and centred... i would ask them for more specifics on how eyeclean it is
