I am in very close to purchasing a radiant cut diamond. I want to make sure I am getting a good price. Any info on the best place to purchase would be of great help to me. Looking at a 2.81 G VVS2 for roughly 22,000 and a 3.0 f vs1 for 26,000. Both cuts are very good and I don''t know much more about the cuts then that. Any thoughts? Thanks!
