Why Does The GIA Colour Grading System Start At D?

Before the grades of GIA were derived from D colour to Z colour, there were few terms present in the diamond world. But these terms were loosely used from Arabic numbers( 0, 1, 2) or the alphabets( A, B, C) or Roman numbers( I, II, III). Moreover, the variety of these systems were without a clear definition. Therefore GIA wanted to do a fresh start for the grading system of diamonds and the colour of diamonds. Hence, the GIA colour chart starts from D colour.
