The Metal Monster by Abraham Merritt

We looked upon a vision of loveliness such, I think, as none has beheld since Trojan Helen was a maid. At first all I could note were the eyes, clear as rain-washed April skies, crystal clear as some secret spring sacred to crescented Diana. Their wide gray irises were flecked with golden amber and sapphire -- flecks that shone like clusters of little aureate and azure stars.

Then with a strange thrill of wonder I saw that these tiny constellations were not in the irises alone; that they clustered even within the pupils -- deep within them, like far-flung stars in the depths of velvety, midnight heavens.
