I have been reading this forum for quite a while and I really enjoy reading all the topics. I am proposing in two weeks and I have been set on a certain diamond for a while. I now though found another diamond withen $100 in price that I am considering instead. One has an HCA rating of .6 and the other a rating of 1.4. How much difference is there? Pictures of both are attatched respectively. Why does the diamond that has poorer symmetry score higher on the HCA than the other that scored the 1.4? Which is going to show more brilliance and fire and scintillation? Comments and recommendations greatly appreciated.
