Finish stone work (4)

Ross

I believe the answer is:

stop

'finish' is the definition.
('stop' can be a synonym of 'finish')

'stone work' is the wordplay.
'stone' becomes 'st'.
'work' becomes 'op' (abbreviation for opus).
'st'+'op'='STOP'

(Other definitions for stop that I've seen before include "Knock out" , "Go no further" , "Refrain from" , "It could be the organist's principal" , "Put an end to" .)

I've seen this clue in The Independent.
