0.73 Carat F-VS2 Ideal Cut Princess Diamond

The second diamond is L/W/D (mm): 5.06*5.06*3.49, while the first is L/W/D (mm): 4.86*4.83*3.42, do you think this will make a big difference in terms of how big the diamond will look when it is set?

Thank you all for your thoughts and suggestions!

I think the H is probably better than the F. A gemologist will review up to 3 for you.

No I doubt you would see any difference is sizes its so small.
