Shining silver lamé creation (6)
I believe the answer is:
agleam
'shining' is the definition.
(I've seen this in another clue)
'silver lame creation' is the wordplay.
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'creation' is an anagram indicator.
'lame' with letters rearranged gives 'leam'.
'ag'+'leam'='AGLEAM'
(Other definitions for agleam that I've seen before include "scintillating" , "Shining brightly" , "Sparkling" , "Bright" .)
