Milky-colored gem (4)

Ross

I believe the answer is:

opal

(Other definitions for opal that I've seen before include "Opaque mineral used a gemstone" , "Semi-precious stone of milky or bluish colour" , "Gem-stone with a milky quality" , "National gemstone of Australia" , "Gem with delicate colours" .)

I've seen this clue in the Newsday.
