$2700 is reasonable for those specs, if you have received it what is most important is that you like it. B2C seems to have a good reputation, and you have a GIA paper with it so I think your in good hands.
Even though it says vs1, the inclusion is so tiny that it could've been a vvs1.
On top of that, Polish is X and sym is VG.
I normally see this type of stone going for $3200+
