Using the HCA for some rounds in the 1.2 range there are two stones that are similar but the HCA score is 0.7 for a 1.225 ct stone that isn''t H&A or ACA, while the othere I am looking at scores higher at 1.1 for a H&A/ACA 1.218 ct. This doesn''t make sense to me that the H&A/ACA scores higher (worse) on the cut advisor... can someone explain?
