Crown and Pavilion angles

drcoll Rough Rock Total Posts: 4 Last Post: 12/19/2002 Member Since: 4/4/2002	Hi everyone. I am interested in a diamond that has a very good score on the Holloway cut advisor. It comes with a score of 0.4 in the BIC range. The problem I have is that the diamond is not certified. It has a sarin report but the angles would give it a low GIA or AGS certificate. The measurements are: Depth 59.1 Table 54.1 Crown angle 31 Pavilion angle 40.4 Cutlet none It says the polish and symmetry is very good and a thin to medium girdle. Is this a diamond to go for -or at least get further appraised? What should I be carefull of? Many thanks for any replies. Dudley

Positive things about this diamond is that it has good spread and low light leakage. IMO, You should consider all this in relation to price. I'll try to post gem file for these proportions.
