Government minister's ringer? (9)

I believe the answer is:

goldsmith

This clue is a double definition.

'government minister's' is the first definition.
(UK politician Zac Goldsmith)

'ringer?' is the second definition.
(Goldsmiths is a jewellers - rings are jewellery)

(Other definitions for goldsmith that I've seen before include "Craftsman; Oliver ---, Irish playwright" , "artisan worker" , "Precious metal worker" , "his output precious?" , "classic author" .)

I've seen this clue in The Guardian.
