### An easy way of calculating crown and pavilion angles ...

Oct 26, 2004· Use the crown angle formula to work out the pavilion angle, plugging in culet rather than table (still works if you plug in 0 if the stone has no culet). eg. With Carolyn's stone, (pav 43%, culet 0.9%) ignoring the culet gives a pav angle of 40.7. Taking the culet into account, the pav is 40.95.
