Agree with Ame, and if you opt for 1.49 carats in VS2 and an I color, you get the bang for your bucks! On the other hand, if you opt for 1.5 carats and higher clarity, you WILL pay the premium. Rather going for VS1 or VS2 is really up to you. They will be eye clean because Tiffany selects eye clean stones. They even sell eye clean SI1, which is even more bang for your bucks. The key is to know your budget. Some people will not go lower than VS1, like Ame, while others cannot even look at less than VVS2. But with eye clean stones, you will not see the inclusions with your naked eyes.
But a VS2 from Tiffany's should be perfectly fine, shouldn't it?
