I just bought my first diamond and hasn’t shipped yet. I noticed it has amazing arrows from the online image and felt like it was perfect with symmetry. Is that a decently likely way to ensure a good cut for a diamond? The table is 59 and crown angle is 33 and pavilion angle is 40.8. Could those angles produce what is shown in the picture? Could a diamond with great arrows still not be ideal and not have a lot of scintillation?
