I was sorting some melee and applying cost to the different parcels. I kept seeing top-light, and top-top-light brown, as well as cape, colored diamonds. I have heard of all these before, but was trying to find out what these color classes are in respect to the GIA color scale. Any Thoughts?

Let me re-phrase that last question...
"Why is it that over the last week, in other jewelry forums, and a few hundred viewers who have seen this exact question have not been able to come up with an answer?"
I wasn't trying to insult anyone, or seem ridiculously impatient. I guess I could have put a little more time into considering everyones feelings before asking the question in such a manner.
...MY BAD DOOS
Anyways, is there maybe too broad of a range when mentioning top light, or top top light, etc.?
Take your time guys, I'm in no hurry.

I am not familiar with the two terms "top" brown... the cape color and its relationship to the GIA scale is easily seen in the above link that shows several different diamond grading scales and how they relate to each other.
I just finished GIA diamond essentials course and was not presented with the two "top brown" terms. If they are darker than GIA Z grade, then they would be classified as fancy diamonds.

The link is partially based on Pagel-Theisen's list and the GIA scale is used most often in the trade. But they are not very good selling depictions, so the old Scandinavian "top wesseltons" etc are still used.
I think Stuller adopted it's own standard for discriminations between the capes. Last week I needed information from Stuller and they replied several times promptly and to my satisfaction.
The Argyle system is a nice one to compare the Stuller images against (if they have them online).

In case anyone is still interested in the original top top light, etc. question the following was an email I received from stuller:
In response to your question about GIA’s translation to Top Light (TLB), Top Top Light (TTLB) and Cape colored diamonds, the color scale equivalent is as followed:
TTLB = K-L color
TLB = M-N color
Cape = O-Q color

Barbara,
Have you ever ordered any of the above mentioned stones from stuller, or any other company? If so, do you remember what you personally would have graded them as? (Using GIA terminology)

I can't speculate on the stones you have, but I wouldn't refer to K-N color as light browns...nor O=Q as Capes. Technically, you could have an N color that was yellowish, not brownish and a Q that was brownish not yellowish.
But, thinking this through I guess that could work if you as long as your documentation reflected exactly what your descriptions were based on. The problem I see using terms like Cape and TLB is that they are somewhat archaic and subjective....but, again, I think you could explain yourself in such a way that it would make sense.
Also, you might want to order a couple of samples of this material from Stuller to make sure you are comparing apples to apples and pricing accurately.
