Diamond for pendant advice

[Izzy70]

What would be these light coloured sections on the diamond that I have tried to highlight in yellow?

My favourites have the following HCA scores:
https://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-4015030.htm This one has a 1.0

And this one
https://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3172023.htm Has a 1.2 score.
Should I select either of these?

Both gorgeous choices - HCA doesn't matter when you have light return images. I'd ask WF to pull both stones and tell you which performs better in person...that's the one I'd go with!

Thank you AC117.
I have selected the second stone above in a custom 6 prong basket in platinum
