I believe the answer is:

opals

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">iridescent gemstones</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>

(Other definitions for opals that I've seen before include "Milky gemstones with delicate colours" , "Iridescent gems" , "Translucent gemstones" , "Milky sparkling gemstones" , "Milky-white stones" .)

I've seen this clue in the Sydney Morning Herald and The New York Times.
