Piece of sculpture (6)
I believe the answer is:
statue
'piece of sculpture' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for statue that I've seen before include "Model figure" , "Solid representation of the human form" , "Modelled figure of a human or animal" , "A carved image or effigy" , "Sculpture representing a human or animal" .)
