I'm sorry if this is somewhere obvious, but I've been searching here and on google and can't find it. There are charts showing how wide GIA color bands are (eg D is narrow, but J is wider, leading some of the discussion around a "high" vs "low" diamond of a certain color). Thanks so much.
Thanks! The one I'm looking is similar to the one shown here listing the colors, but the (visual) size (width) of the different segments is different ( so eg d occupies less space than j), instead of all the colors having the same size segment.
