Duck, in white alabaster (4)

I believe the answer is:

teal

'duck' is the definition.
(teal is a type of duck)

'in white alabaster' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TEAL' is hidden within 'white alabaster'.

(Other definitions for teal that I've seen before include "Small, short-necked duck" , "Small freshwater duck and colour" , "Duck - dark greenish-blue" , "bird" , "Duck; greenish-blue colour" .)

I've seen this clue in The Daily Express.
