diamond dust
Ice crystals suspended in clear, calm air near the ground on extremely cold days, glittering in sunlight like falling dust. Not a cloud, not precipitation — the air itself has frozen and is slowly settling. Diamond dust produces halos, sun dogs, and light pillars.
Etymology
Descriptive English. Diamond (from Latin adamas, “hardest metal,” via Greek) + dust (Old English dūst).
