Hello,
I found that some online stores provide a GIA/AGS + real ASET combination reports.
Here is the question "Can I say a diamond would have great light performance in real life if it associated with exact Tolkowsky Cut (34.5 Crown, 40.8 Pavilion) in GIA and a good real diamond ASET?" Is there any information that these two reports do not take into considerations but meaningful to estimate a diamond light performance?
A problem raised here for me is the deviations of the diamond's proportion measurement, for example, GIA has a 0.5degree interval for the average crown angle. So a Tolkowsky Cut diamond show on GIA might not be an "exactly" Tolkowsky Cut diamond.
I guess advanced Sarin report, which I can also get from one of the online stores, maybe works here
Because it provides all facets' measurement instead of a range or an average number. But I don't know how to implement all these measurements from Sarin report.
It would be great if you could link me some pre-discussed threads and even greater a paper about these questions
I really appreciated all these information throughout my way to THE diamond
Thank you
