Crane made of mother-of-pearl (5)
I believe the answer is:
nacre
'mother-of-pearl' is the definition.
(I know that mother-of-pearl can be written as nacre)
'crane made' is the wordplay.
'made' is an anagram indicator.
'crane' with letters rearranged gives 'NACRE'.
'of' is the link.
(Other definitions for nacre that I've seen before include "Mother of pearl" , "Mother-of-pearl from shellfish" , "Mother-of-pearl - crane (anag)" , "valuable material" , "Constituent of inlay furniture" .)
