I'm not sure what your question is... GIA will grade a diamond's colour as "natural" if they are confident it is of natural origin, and they will denote it as "enhanced" if the diamond has been processed in ways that (are likely to) have altered its colour. If they cannot determine the origin - which often happens with greens - they will call it "undetermined". There is no way (short of corrupting many GIA employees, which I'm sure is not what you mean) in which you can "get" a natural colour grade for a stone where GIA is not certain of the origin.

"How" to get GIA to grade a diamond is pretty simple, and explained very well on GIA's site. http://www.gia.edu/gem-lab-service/colored-diamond
