Shone like gold we refined (6)
I believe the answer is:
glowed
'shone' is the definition.
('glow' can be a synonym of 'shine')
'gold we refined' is the wordplay.
'refined' indicates anagramming the letters.
'gold'+'we'='goldwe'
'goldwe' anagrammed gives 'GLOWED'.
'like' is the link.
(Other definitions for glowed that I've seen before include "Shone" , "Gave out light - like some worms?" .)
