A word that describes something whose purpose is to be fancied depends on who fancies the object. The implications are different.
Using the example: The [word] vase stood in the middle of the room.
If the vase standing in the middle of the room was rather plain but some action was taken to make the vase fancy, a word such as decorated would apply. The decorated vase stood in the middle of the room ready for view.
If the vase standing in the middle of the room was fancied due to desirability placed upon owning a piece by the artist who created it, say, a different circumstance applies given the same wording.
