by ceg » Apr 20, 2017 at 6:27 PM I purchased a diamond (2.5 carat, I, vvs2. Ideal round, medium fluorescence ) a few days ago that has a hca score 1.8 and is considered a FIC cut. I have been reading about this and found that these cuts are rare. I bought this from blue nile and talked to a few experts for their advice. All said it was cut well. It did have pics and looked great to me. I guess I am getting worried. Is FIC less desirable than TIC or BIC?
