Diamond Dust

weather · ice · polar regions · crystals

Tiny ice crystals. Diamond dust is made of super small ice crystals so light they float through the air like glitter. They're so tiny and sparkly that they catch the sun and make the sky shimmer beautifully.

Falls from clear skies. Unlike regular snow, diamond dust happens when the sky looks almost clear and blue. You can watch it falling while the sun shines, which makes it extra magical to see.

Needs extreme cold. Diamond dust only forms when temperatures drop far, far below freezing. It's so cold that water vapor in the air turns straight into ice crystals without becoming liquid water first.

Loves polar regions. You'll find diamond dust most often in Antarctica and the Arctic, where it can stick around for days or even weeks without stopping. But it can happen anywhere on Earth that gets cold enough.

Ground-level cloud. Diamond dust forms really close to the ground, not way up in the sky like regular clouds. That's why you can see it so clearly and watch the crystals sparkle all around you.
