Give finest ring to women (6)
I believe the answer is:
bestow
'give' is the definition.
(bestowing is a kind of giving)
'finest ring to women' is the wordplay.
'finest' becomes 'best' ('best' can be similar in meaning to 'finest').
'ring' becomes 'o'.
'to women' becomes 'w'.
'best'+'o'+'w'='BESTOW'
(Other definitions for bestow that I've seen before include "Confer, donate" , "Set bow to give" , "'Confer, present (6)'" , "Present, donate" , "Confer (an honour)" .)
