I believe the answer is:
cameo
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">carved brooch</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for cameo that I've seen before include "Part in movie" , "Small role - gem with a figure carved in relief" , "Piece of jewellery with carved portrait" , "Small part for star actor" , "Carving in relief, on a brooch say" .)
