I’m looking at this diamond: https://www.jamesallen.com/loose-diamonds/princess-cut/2.02-carat-d-color-if-clarity-sku-16396947
I see that its 67.5 table and 66.7 depth don’t fall within the proportions you recommend for princess cuts on this site. Though it is listed as having an “ideal” cut according to the James Allen website.
What should I expect for this diamond? Has it been cut to maximize yield instead of brilliance? Can we tell what the visual performance will be like?
James Allen’s “ideal” designation is arbitrary. And my recommended proportions are only a guide based on empirical observations of AGS 0 Ideal princess diamonds. My recommendations are meant to ensure sufficient crown height, which is not listed on the grading reports for natural diamonds.
However, crown height is listed on IGI reports and both of your choices have sufficient crown height. Despite that, they both have a more watery appearance. If you compare them to something like the diamond below, I think you’ll notice how much brighter the 2.12 D VS1 looks and how much more contrast there is with a more even scintillation pattern (distribution of dark and light facets). IF clarity is generally overkill – you won’t be able to tell a difference between it an this VS1.

Got it, thanks for the explanation!
Also, how would you compare that diamond to this one?
