White mineral used for carving (9)
I believe the answer is:
alabaster
'white mineral used for carving' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for alabaster that I've seen before include "Sort of gypsum" , "Carved form of gypsum" , "Stab a real odd white mineral" , "Altar base (anagr.)" , "Blast area for white mineral" .)
