Cheap ornament (7)
I believe the answer is:
trinket
'cheap ornament' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for trinket that I've seen before include "Inexpensive ornament" , "Charm" , "Ornamental item of little worth" , "Knick-knack" , "Ornament of little value" .)
