Ginger isn't dancing in jewellery (6,4)
I believe the answer is:
signet ring
'jewellery' is the definition.
(signet ring is a kind of jewellery)
'ginger isn't dancing' is the wordplay.
'dancing' indicates an anagram.
'ginger'+'isnt'='gingerisnt'
'gingerisnt' with letters rearranged gives 'SIGNET-RING'.
'in' is the link.
(Other definitions for signet ring that I've seen before include "Personal seal" , "that 9,16 [QUEENS MARKER] reportedly uses" , "band used to make impression" , "it makes an impression" , "Item of jewellery, often engraved with an initial" .)
