Crossword Genius

Grin about jewellery (4)

Ross

I believe the answer is:

ring

'jewellery' is the definition.
(ring is a kind of jewellery)

'grin about' is the wordplay.
'about' is an anagram indicator.
'grin' anagrammed gives 'RING'.

(Other definitions for ring that I've seen before include "0?" , "Form circle around" , "Hoop" , "Circus space; surround" , "place for fight" .)

I've seen this clue in The Mirror.
