I have noticed that the pics on James Allen website seem to look nicer than those on Blue Nile. After running the cut estimator on stones from Blue Nile and finding them to be mathematically great cuts, they still don’t show those nice black arrows that lesser James Allen stones have. Is this just the difference in photography or will these James Allen stones look better in person as well?
thanks in advance,
It’s the difference in photography. Blue Nile isn’t as consistent in their setup, both in their angles and their background. The arrows won’t always be as clear for a well-cut diamond like they are for JA.
However, the same proportions that you find from my computer-vision based approach for JA can also be used to supplement the cut estimator proportions for BN. The higher pavilion angles for AGS 0 Ideals won’t show the arrows as well in both photographic setups.
