Have you run them through the HCA tool? Look for ones that score 2 or below.
Do you know if they are eye-clean?

GIA 2196421830 - HCA 1.2
GIA 6167670190 - HCA 2.0

Have no idea which one is better, I can see inclusion both of them under magnifying glass.

Will the measurement below show significant difference on the diamond?

a. 6.45 - 6.48 x 3.95 mm
b. 6.34 - 6.37 x 3.97 mm
