A little concerned about HCA discrepancies

[DoctorGirly]

Hi everyone,

I am getting a 2.5 ctw 5-stone band made, but I am out of town, can't see the diamonds in person, and can't get idealscope images. My jeweler sent me the GIA certs, and after inputting all the information into the HCA, I am concerned. 3 of the diamonds are "Very Good" all across the board, but the other two have Good to Fair ranges, see all below:

The strong performers:

GIA 5151378134
Depth
62.0 %
Table
57 %
Crown Angle
34.0°
Pavilion Angle
41.2°

GIA 5151376905
Depth
60.8 %
Table
57 %
Crown Angle
34.0°
Pavilion Angle
41.2°

GIA 2155378180
Depth
60.7 %
Table
57 %
Crown Angle
33.5°
Pavilion Angle
41.2°

The weaker performers I'm worried about, especially with respect to their fire and scintillation:

GIA 5151376900
Depth
62.3 %
Table
56 %
Crown Angle
34.5°
Pavilion Angle
41.4°

GIA 2155021583
Depth
61.4 %
Table
57 %
Crown Angle
34.5°
Pavilion Angle
41.4°

Should I say that I am unsatisfied with the last two diamonds and have him replace them? I could potentially make them the stones on the ends, but if they are going to be significantly weaker than the other three, that doesn't sit well with me. Or, will the differences be negligible across the 5 F VS2 Ex half-carat diamonds? Is it worth waiting a week to look at the set in person? Any advice would be appreciated!

I am not sure I'd accept very good across the board, either. I'd want excellent for everything except spread is often very good. Were all of these GIA excellent cuts?

I'd try to stay in this range:

crown angle 34-35

pavilion angle 40.6-41.0

Those first two might have better scores if the pav angles were 41.0. And the problem with the last two is definitely the pav angles. I would ask for those to be replaced for sure.

What style 5 stone are you making? Five half carat stones can be challenging to fit across the finger sometimes.

And do you have to work with this jeweler? I'd want pictures and idealscope images for sure.
