How is this diamond:

It is IGI graded though, is it not as good as GIA graded? I had this reserved already but would like your opinion on this before place the order, thanks.

We don’t recommend IGI certified stones. They are looser in grading than GIA or AGS (https://www.diamonds.pro/education/igi/). GIA and AGS are the most consistent and reliable labs. I’d recommend sticking with GIA/AGS certified diamonds only.

I see, so could you please recommend a good diamond from James Allen? I want an eye clean 1 carat diamond for my halo ring setting, similar to the one I showed you.

How’s this one?
