GIA Certs

[abbott]

When the "X" on the color grading scale of a GIA cert is located more to the right or left rather than in the middle of the "box".. does that mean that the color is more toward the higher or the lower end of that particular color grade... In other words, if the X in the G box is located toward the F.... Does that mean it is a higher quality G... or is a G a G no matter where the X is in the box....

No labs grade diamonds as high or low withoin a color grade

So, how do they decide when it is "iffy?" Isn''t that the most subjective part of grading??

It''s probably like inserting a document in a typewriter (remember those?!!) and not getting the "X" is the center of the blank space.

Garry, that wine really has you in a forceful mode. ImaGem technology is able to grade accurately to 1/3 of a GIA colorless color or near colorless grade; high, medium and low, but one is left still with diamonds that would cross over to a split grade such as Low F/High G. There is no getting around such a situation and no one will be pleased with it. Anyone who gets a low F won't want to pay for F color when it still is a GIA F. Would they prefer to pay a G price? I'd bet that's exactly what would happen, and no dealer would stand for it. We could divide the richer colors into more partial grades than 3 in each grade. Maybe this will be important when we grade fancy color diamonds, but we are not at that point quite yet. Certainly there is room for 5 or even 10 degrees of fancy color range in a scientific system geared for marketing and defining FANCY color diamonds. Colorless and near coloress diamonds are well enoughdefined by GIA grading. It is tough enough for all of us. The placement of the "X" is accidental.

We'd be making losers, in each color grade, of perfectly nice diamonds with partial division classifications.

Who would want a low D if they were simply paying for a GIA D? We need to be sensible in what we offer as information. Sometimes, too much information is just too much.
