Take out some diamonds (3)
I believe the answer is:
ice
I believe this clue is a double definition.
'take out' is the first definition.
(both can mean to assassinate or kill)
'some diamonds' is the second definition.
(slang term for diamonds)
(Other definitions for ice that I've seen before include "A state of water" , "Decorate a cake" , "Diamonds (sl)" , "Cold stuff used in enticement" , "Glaze" .)
