Okay, I have read the tutorial from Garry, but I''m still not sure I understand. It seems like it''s saying that most consumers did not perceive a negative effect from less-than-ideal symmetry in a round brilliant diamond. Is that right? Can a very good or good symmetry diamond be worth looking at? I''ve pretty much restricted the search to excellent polish, excellent symmetry (or ideal, depending on the lab), and I''d probably keep the high polish grade, but is it okay to come down some on symmetry?
