How Different Labs Grade Colour

The gia and ags have different colour grading scales of which to determine the colour of a diamond.

While GIA is the leading and most respected of the grading laboratories, there are other highly respectable gemological laboratories that grade diamonds for colour as well. The primary one and most respected of these is AGS, American Gemological Society. EGL, European Gemological Society, and IGI, International Gemological Institute, also have colour grading scales, which are similar in nomenclature to GIA's.

AGS uses a colour grading scale that is comparable to the GIA colour scale, but it is not as comprehensive, and lists its grades using numbers as opposed to GIA's letters. The AGS colour grade scale runs from 0 to 10, with 0 corresponding to the GIA's "D" and 10 corresponding to the GIA's "V-Z". The AGS grading scale, in comparison to GIA's runs as follows:
