When it comes to what it means to be fake I guess that a fake is something that resembles something else but is different in some fundamental way (usually it is also trying to pass itself off as that something). So providing you have a full description of what makes X X you could also have a description of what a fake X is.

I'll have to ask him which branch of logic allows us to consider a
fake diamond as "a special case of a diamond".

Yes Ryan and Dembadon, very interesting when you consider questions about the existence of reality and the theoretics that lead to these types of conclusions.
Roger Penrose talked about the Wick rotation during his debate with Stephen Hawking in "The Nature of Space and Time".

This a useful tool in QFT. One replaces t with it by means of a rotation of the time axis. This translates Minkowski space into Euclidean space.
