Newbie here, when doing a bit of research I assumed that an Excellent HCA score = Ideal Cut = beautiful firey sparkle.
But looking at this diamond, for example (waiting for photo and idealscope image, but I like the strong fluorescence )
http://www.jamesallen.com/diamonds/I-VS2-Ideal-Cut-Round-Diamond-1429488.asp
GIA report only grades the cut as Very Good, whereas the HCA score is 0.9 Ex (VG-Ex-Ex-Ex)
What would have brought the GIA grade down? and would the high HCA score be a better indicator of performance?
Also, if a H&A cut is 'perfect' then why do H&A diamonds seem to score higher than 2 on the HCA scale?
many thanks...
