Most sites that attempt to give price ranges do not include the fancy yellows. Is there an general rule of thumb that would equate the yellow diamonds to white diamonds: somethjing like Fancy Light Yellow is similiar to H-I''; Fancy Yellow is similar to F-G; Fancy Intense is similar to E and Fancy Vivid is similar to D - or something like that? I am looking at a fancy yellow (not light or intense) that is 2.2 KT, VVS2 for $6800 per KT. It seems to have good proprotion based on everything else I''ve read but I am at a loss to put it in perspective. Any other resources I can access on this?
