opalescence

Across the violet surface of the Mediterranean and the crystal opalescence of the evening sky the music fell voluptuously.

In a certain aspect, there plays over this spot a violet opalescence of exceeding richness.

And in the midst of it all the girl shone like the one evening star in the mystic opalescence of twilight.

Far overhead there was one fleeting glimpse of a pinpoint of dull opalescence reflecting the rays of the dying sun.

The filtrate from these precipitates containing only fractional residues of acetone still shows opalescence.
