Relief maybe created by overturned cup result (9)
I believe the answer is:
sculpture
'relief maybe' is the definition.
(I know that embossment is a type of sculpture)
'overturned cup result' is the wordplay.
'overturned' is an anagram indicator.
'cup'+'result'='cupresult'
'cupresult' with letters rearranged gives 'SCULPTURE'.
'created by' acts as a link.
(Other definitions for sculpture that I've seen before include "Artwork produced by carving, moulding etc" , "Carving art" , "Three-dimensional work of art" , "3-D art form" , "3-D representation" .)
