Hi,
After receiving great feedback from the folks here, I've decided to go for a WF ACA. However, picking one out from several within a price range is quite challenging as they're all beautiful. Obviously, it boils down to color, size and clarity.
But proportionwise, I understand that crown and pavilion angles are critical for light return and should complement each other should one lies at the edge of its recommended range (crown: 34-35; pavilion: 40.5-41).
My question is since all ACA's have earned AGS 0 Ideal in light performance (and the requisite for earning the ACA brand goes beyond simply having great proportions), how big of a factor then do crown and pavilion angles play in light return in this situation?
Below are 3 examples. Unfortunately, the last listing doesn't have a video clip for comparison. Color and clarity difference aside, the first diamond has a 35 degree crown angle while the others are at 34.7 and 34.5. They all have slight variations in the complementary pavilion, star/LG%. Does it make sense to think the 35 crown is less favorable stone than the other 2? It's video clip is quite appealing, however.
