Me again. I don't think I'll be able to find an eye-clean, G colored, ideal cut, 1.5 ct round diamond for $15,000. In order to stay in my budget, where do you suggest I compromise? Drop to a VG cut? Drop to H color? Or go smaller? My budget would allow a 1.3 ideal cut stone in F/VS2. Is the upgrade in color/clarity going to make a difference in beauty? I had an E/VS2 diamond so I'm use to a very white diamond so I've really shied away from going below G.
