Variety of gypsum (9)
I believe the answer is:
alabaster
'variety of gypsum' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for alabaster that I've seen before include "White stone carved into ornaments" , "White substance" , "White translucent form of gypsum used for statues, vases etc" , "Translucent white gypsum as found carved into ornaments" , "Form of gypsum used for carving" .)
