Jewellery I found in Scarlett’s place (5)
I believe the answer is:
tiara
'jewellery' is the definition.
(I've seen this before)
'i found in scarlett's place' is the wordplay.
'found in' indicates putting letters inside.
'scarlett's place' becomes 'tara' (ref to Gone with the Wind).
'i' put within 'tara' is 'TIARA'.
(Other definitions for tiara that I've seen before include "Woman's headdress for very formal occasions" , "Ornamental head band" , "Ornamental headpiece" , "Woman's head ornament" , "Crescent-shaped headdrsss or Pope's diadem" .)
