Ana, I just read the link you provided. They do overlap to some extent. AGS has ideal outside GIA''s excellent, and GIA has excellent outside AGS''s ideal, but there is some overlap. I think this is what you meant to say. From the one week that I''ve spent studying this (not much), my impression is that AGS''s 0 ideal is probably a little too narrow and GIA''s excellent is probably too broad. But anyway, I''m happy to be done w/ the diamond buying experience. This site and all of you have been a really big help. Thank you all!
I do have a question for those who are experts w/ the HCA. Does it account for the star length? According to the AGSL charts, the diamond I bought is AGS 0 on the 50% star lengths and AGS 1 on the 60% star lengths. My 1.05 has a star length of 55%, right in between. The HCA says that it is within the AGS 0.
I suspect that it assumes a 50% star length, as you only input table and depth percentages, and pavilion and crown angles. I don''t see how you can calculate the star length from these parameters.
