I am trying to run the Hollaway Cut Adviser on a diamond I am interested in buying. Since the diamond is GIA certified, it only has the depth% and table %. How do I calculate the Crown, Pavilion and Culet?
Also, what is the name of the free software that calculates the diamonds'' proportions and deciphers whether the diamond is good? Does this program use the same information as the HCA does? Thanks in advance.
