A, AA, AAA: What does this mean?
from Gem 2000
These are terms often used on the phone from jewelers who are ordering gems for their specific calls. However, some consideration should be exercised before using these terms when ordering colored gemstones. First of all, these terms are not scientific in any shape or form and cannot be equaled to using clarity or color grades in diamonds. Calling a diamond dealer and saying you want a AAA or A diamond will not work. You are better off saying a VS,GH color, or an I,K color, or if budget dictates quality say about how much a carat you can spend on the stone.
