All I am saying DG is that if the stone has no part of the natural that intrudes into the inside of the stone then it is not by word definition an "inclusion" it is a surface feature
But different labs make different rules to "talk" to the world.
Arguably a perfectly flat natural is not an inclusion, and a rough one like this is not - but it is all about grading rules.
HRD established and published rules that OctoNus computerized into their rough diamond scanners. But GIA backed away from any such standardization when it was being worked on in the 1990''s by a standards body.
