Shine, getting fantastic result (6)
I believe the answer is:
lustre
'shine' is the definition.
(lustre is a kind of shine)
'fantastic result' is the wordplay.
'fantastic' is an anagram indicator.
'result' is an anagram of 'LUSTRE'.
'getting' acts as a link.
(Other definitions for lustre that I've seen before include "Gentle sheen, soft glow" , "Sheen - glaze" , "brilliance" , "effect of reflected light" , "Period" .)
