Questions re: radiant cut with "X" and "O" pattern

[Jillyville]

Hi everyone! I'd like to know more about the cut quality of my diamond. It was purchased from a reputable online jeweller as an ideal radiant diamond. I'd like to know if it's normal (quality) to see this "X" and "O" pattern in a square radiant diamond. I hope you can see what I mean when you look at my pictures.

I can see a slight "x" in the second to last picture, but without an aset image, we can't tell you how good of a cut it is...

The light conditions and pictures are too blurry for any meaningful discussion. The edges of the stone do seem bright though.
