This is 0.9 carat? Wow it looks like it's more than 2. Mine is 2+, and the diamond looks about the same size on my chubby finger lol

Yes I remember HCA score now. Hubby used that calculator to evaluate every diamond before he proposed. He eventually got mine from White Flash. 0.9 is very very good. Blue Nile is a great place. Beautiful diamond and it looks great on you!
