Question about buying a round brilliant.....

[windowshopper]

okay i dont really know "rounds" and I am in search of a 1 carat for a pendant. I find looking through all the rounds EXHAUSTING. I am pretty much focusing on G VS 1''s and 2''s--ideal cut. This is my dilemma: I look and find half a dozen 1.01, G , VS2--all IDEALlIDEAL or Ex/Ex. Are these all safe bets............what are distinguishing differences. My goal is an amazing cut set in a micro pave''d bezel mount.................
