Here is the feedback I've received from the gemologist.
Diamond #1 has very nice light performance and has the best scintillation/sparkle of your selections. Its brightness is consistent throughout the diamond and it has a higher/whiter "H" color. As expected, it is perfectly eye clean and its inclusions pose no durability concern. I strongly recommend this diamond for your purchase because our gemologist favored it the most.
Diamond #2 is also very bright but doesn't sparkle quite as much as diamond #1. It has a true "G" color that appears perfectly white but you might be able to pick up on the feather close to the girdle. The good news is that most of the feather will be able to be covered by a prong.
Diamond #3 is bright but has a very slight amount of grayness under its table. It faces eye clean and it has a true "H" color.
Thank you for your feedback thus far. Before I go with #1, do you all think these are excellent quality diamonds/images? #1 & #3 are AGS 000, #2 is GIA EX/EX/EX. I'm a little concern that #1 is best b/c of my poor selection in the 3 diamonds...
