Carol fashioned type of jewellery (5)
I believe the answer is:
coral
'type of jewellery' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'carol fashioned' is the wordplay.
'fashioned' indicates an anagram.
'carol' anagrammed gives 'CORAL'.
Can you help me to learn more?
(Other definitions for coral that I've seen before include "Pinkish-orange colour" , "Shade of pink" , "Tiny animal forming reef" , "orange-pink colour" , "Hard pink substance formed by skeletons of tiny sea creatures" .)
