Which diamond would you pick?

I'm in no way an expert, but they both look very nice. If they're the same price, I guess the F seems nicer, less imperfections on the certificate. I'm not sure that the size difference would be very meaningful at that point but again, I'm sure someone else will weigh in. I'd be over the moon with either one!
 
Both score below 2 on the HCA scale. The 1.71 looks a lot cleaner. Can you get the idealscope images? I would lean towards to the 1.71 personally.
 
The 1.71. Clouds are the first item listed on what is affecting the clarity and it may affect the light transmission of the stone.
 
I would choose the 1.71.
 
Thanks all, I really appreciate your opinions!
 
The F, VS1 is much better by color, clarity and cut!
 
Set a carat weight least in light of the beneficiary's inclinations. On the off chance that they have their heart set on a one carat jewel, even the most delightful half carat stone will be a failure.
