  • "The last bits of moisture condensed and froze and fell glittering in tiny crystals from the cloudless sky—diamond dust, meteorologists call it, a sign that the coldest, driest weather is building in."
    —David Laskin, The Children's Blizzard (New York: HarperCollins, 2004), 204

  • A ground-level cloud composed of tiny ice crystals that generally forms under otherwise clear or nearly clear skies. Sometimes called clear-sky precipitation. It is most commonly observed in Antarctica and the Arctic, but it can occur anywhere with a temperature well below freezing. In polar regions, diamond dust may continue for several days without interruption.
