Great question.
1.74CT GIA H Triple Excellent
.50CT GIA H Triple Excellent
.50CT GIA G Triple Excellent
By far, aside from color, the most important factor for me was the excellent cut, excellent polish, and excellent sym for the brilliance. I am lucky and have two friends that are GIA certified so I have a lot of resources.
For anyone curious what we are talking about, compare GIA H color vs EGL H color. You basically pay for rating. If the rating is wrong, you still pay for it.
