Lost vintage ceramic vase with unique blue and white pattern last seen on a porch near College Station after a dinner party.

I lost a beautiful vintage ceramic vase that has a unique blue and white pattern. It was last seen on the porch of my friend's house near College Station after a weekend dinner party. I believe it may have accidentally been forgotten there or picked up by someone thinking it was theirs. It's quite special to me as it was a gift from my grandmother, and I would appreciate any help in finding it.
