Gemstone (4)

Ross

'gemstone' is the definition.
(I know that opal is a type of opaque gem)

This is the entire clue.

(Other definitions for opal that I've seen before include "Milky-white mineral" , "Iridescent gemstone" , "it may be highly valued" , "precious jewel" , "Translucent gemstone" .)

I've seen this clue in The Guardian, The Times, The Telegraph, The Independent, the Evening Standard and The Mirror.
