Charm bracelet finally after a cross (6)
I believe the answer is:
amulet
'charm' is the definition.
(amulet is a kind of charm)
'bracelet finally after a cross' is the wordplay.
'finally' indicates one should take the final letters.
'after' means one lot of letters go next to another.
'cross' becomes 'mule' (I've seen this before**).
The final letter of 'bracelet' is 't'.
'a'+'mule'='amule'
't' after 'amule' is 'AMULET'.
(Other definitions for amulet that I've seen before include "Charm to protect from evil" , "Protective trinket" , "Protective charm" , "A type of lucky charm" , "Magical charm" .)
