Queen in Italian necklace (4)
I believe the answer is:
anne
'queen' is the definition.
(I've seen this before)
'in italian necklace' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ANNE' can be found hidden inside 'italian necklace'.
(Other definitions for anne that I've seen before include "One of the Bronte sisters" , "She married Shakespeare" , "Queen seventeen hundred and two to seventeen fourteen" , "23's sister" , "Name of dead queen!" .)
