I have been read that crown and pavillion angles on all the facets should be as tight/close as possible. Also the culet should be none. For a nice stone. Looking at two stone I have some questions.
Stone 1: Crown angle 33.6-34.0 (the range is only 0.4 degrees, pretty good I guess) Pavillion angle 40.3-41.2 (the range is 0.9 degees off, is this BAD? What should the range be within to one another???
Stone 2: Crown angle 33.8-34.2 (range 0.4 degree) Pavillion angle 40.6-40.9 (range o.3 degree) Is this a better stone than Stone 1???
Also on both of these stones the culet is none on the GIA report but on the sarin Stone 2 reads very small culet. How come the difference between the two? Also is a very small culet bad? What is an ideal Culet?
For the girdle, what is prefered? I thought med to sl. thick is preferred. But is thin to medium necessarily less ideal??
thank you for everyones help.
