I've been reading a lot here, but I haven't been able to find my answer. Perhaps I just can't grasp it is the problem too. :wall:

With Whiteflash aca's, will some stones have more white light return, and appear whiter, at the expense of loosing fire? Do some stones have a lot of fire, but will appear more sliver? I read a lot of threads, but I can't find how you can tell this and I just don't understand. Is there a simple method to tell how a stone will perform in regards to having more white light/less white light. Or more fire/less fire? Thanks

WF ACAs are cut to an extremely tight set of Tolkowosky Ideal Cut (TIC) parameters - overall performance of ACAs should be consistent from one ACA to another, barring very slight nuanced differences due to table size and star/lgf combinations. It is unlikely a person would detect by eye a difference in white light return and/or fire in comparing one ACA to another.

ACAs are TIC diamonds with AGS ideal cut grading, meaning without significant deduction in brightness, dispersion, contrast and leakage. Depending on light condition and viewing distance, all ACA should have equally excellent fire and white light return.

Light performance characteristics may vary depending on table size and lower girdle height. Good old gold has excellent videos on these topics on its youtubr channel.
