Today i witnessed something that i had never witnessed before : diamond dust. It was beautiful !
Diamond dust is a ground-level cloud composed of tiny ice crystals. Diamond dust generally forms under otherwise clear or nearly clear skies, so it is sometimes referred to as 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 Polarregions diamond dust may continue for several days without interruption.
