Due to not being sure if who ever posts first wins, we're going to post our answers now...
For those who I didn't communicate with, I hope you're not mad, but until I hear further, me and 2 other members wanted to post ASAP... Gosh I hope you're not mad!! If we find out that it's not on a first come first basis, I will wait till I hear from others. I, along with the members I talked with are POSITIVE of our answers as we have concrete proof Here offered by Tribe EnAblers are the final answers to the challenge set on Tuesday May 29th:
1. Why doesn't GIA use A, B & C when grading color in diamonds?In a nutshell? They wanted a fresh start. But GIA states:
"Why does the GIA color grading system start at D? Before GIA introduced the GIA D-Z Color Grading Scale, a variety of other symbols were loosely applied throughout the industry. Not only were A, B, and C used without clear definition, but some dealers, taking a cue from the poultry business perhaps, started grading their diamonds double A (AA).
Other systems used numbers-both Arabic (0, 1, 2, 3) and Roman (I, II, III). Most dubious of all were systems that relied on descriptive terms like "gem blue" or "blue white." Terms like these are notoriously susceptible to misinterpretation.
So the creators of the GIA Color Scale wanted to start fresh. They wanted symbols that would not have any association with earlier systems. Thus the GIA scale starts at the letter D. There may be some people still clinging to other grading systems, but no other system has the clarity and universal acceptance of the GIA scale."
