Since you are so color sensitive, I would not buy a ring with yellow flourescence.
My original Tiffany ring was a 1 carat G VS2 and I upgraded last year to a 1.9 I VS2, with medium blue flourescence. Both rings were triple EX and faced up very white to me (I actually couldn't tell the difference), and I much appreciate the larger size.
I am not an expert, but I do know that blue fluorescence isn't necessarily bad (Brian Gavin sells a line- Brian Gavin Blue, for instance). I have not read good things about yellow fluorescence, however. I think it is rare.
You are paying a huge mark up for the Tiffany name (nothing wrong with this, my ring and 3 bands are Tiffany)- but what you choose should be perfect in your eyes.
