Ok, so my plan is to propose this coming Christmas/ New Years. I'm looking for a solitaire and round diamond. The setting I'm leaning towards is the tiffany half round on Brian Gavin's website. I know about the 4 C's and that is about the extent of it. I know I'm going to want an ideal or excellent cut and something around a VS2 cut or that is not unaided eye visible. My issue is I'm not really sure about all the measurements, girdle, etc. So if anyone can show me some ideas of what would be the best value for my money I would appreciate it. My budget is around 6k but would flex to 7k if need me. Looking for a stone that is at least 1 ct. up to 1.5 ct. Thanks
