I started looking for the traits you mention in your round diamond guide. I picked up a couple was hoping you could guide me a bit.

Also do Blue Bile pictures just suck? I can’t seem to find a diamond with the defined 8 arrows you mention in the guide.
Both of your diamonds are nice with good proportions and symmetry. Blue Nile’s photography is not quite as consistent – sometimes the black arrows will show up as white reflections and then turn black if you rotate them a little. I think those cases are fine with optimal proportions.
You could save some money by going with lower clarity. For instance, the 0.62 G SI1 would be about $200 cheaper than the 0.59 G VS1. You could go up a grade in color with the 0.6 F SI1. And then for the same price as the 0.62 G VS1 you could jump to a 0.73 G SI1. All three diamonds should be eye-clean; the black crystal around 12 o’clock in the 0.6 F SI1 would be hidden under a prong.
