The HCA is mainly for rejecting dubious combos.
It does you a solid by postulating what *may be* implications for fire and scintillation. But that’s based entirely on 2D assumptions. It doesn’t take 40 of the facets or optical precision into consideration.
Summarized: The detailed info you have on the make of your diamond, including the AGS 0 grade specifically, trumps the fire/scint postulations the HCA gives as a favor “in the blind.”
Edited to add: I was composing my reply when @sledge posted. +1 to the comments above.
Proportions is hard to tell but if you can provide the scopes would be more easy to comment on your diamond light performance.Despite the very good score on scintillation, will this diamond still have a good balance of white sparkle vs fire? Will it have good contrast? I know it has thicker arrows due to the shorter lgf’s (75%).
