Dear Leonid and Lawmax,Thank you very much for your reply.The measurements I wrote came straight from the certificate.The diamond itself looks great. I even looked at it under different lights and with and without lenses.I liked how it looked, but I wanted some expert to tell me if a table of 81% and depth of 66.20 are recommended for a radiant cut, 0.54 ct, which measures 5.75x4.27x2.83 MM.Thanks again! I really appreciate your time.
