LOL Thanks!

I haven''t learned about much other than round diamonds, simply because thats all I needed to learn.  You can definitely get something nice for that price around $5000 though..

I too don''t know much about princess cuts (I was shoppinng for a Round), but you have roughly the same budget I did.  Platinum vs. White gold will make a big difference on what you can spend on the diamond, so I''d figure out which you are going to buy and then you''ll know how much you have left for the diamond (Platinum rings will be anywhere from $500-$1500 on average i''d guess...white gold $200-$500 maybe?).  If ''size'' is important for your diamond, then look for something with an excellent cut (I don''t think they can classify Princess cuts as ''ideal''...someone correct me if I''m wrong), with a little lower color and clarity.  Not sure if Princess cuts show more color than rounds, but you could look in the G-I range, with a clarity in the VS2-SI1 range maybe (provided it is ''eye-clean'').  I''d be willing to bet you could find a diamond such as this for $4,000-$4,5000, and maybe less?! 

Just some thougts...again, not much experience with Princess cuts so I could be way off...
