FYI - I have not read this thread but did notice you took a photo in sunlight and the diamond looked black. That is really good. Bad cuts look good in direct sunlight.
I wrote about that a few times here. And have a blog on the topic - you should be able to find it.
As Karl wrote - this is on the verge - if the pavilion angle is 41.11 then it will look great.
Personally I think +2ct for colorless you should be at G, but it is a personal thing.
And one of the diamonds @mrs-b found IS a G 3.03 G, SI1-- so sounds like in line with your preference!
