What do the numerical scores of the HCA represent ? I know you have to look at the stones and compare them at some point, but what can I know about a stone and the differences between individual stones based solely upon their HCA scores? If I had three AGS000 stones of the same color and clarity and carat and #1 gets a .5, #2 gets a 1, and #3 gets a 1.9 what is this telling me about the differences between the stones? I apologize if this has already been explained to death, but I did a search on the topic and didn't find an answer.
