High Priority - Free Web Icon

This High Priority icon is part of an icon pack of 68,900 web icons. Icons are available in PNG, SVG, CSS, PDF, and EPS formats, as a font, and in other vector formats. Unlike other icon packs, our web icons are designed by a single designer, guaranteeing the consistent style and quality.
There is a single diamond shape, and in the center of the diamond shape is an exclamation mark. There's no other detail to the sign or any other marking on it, it seems like a warning sign of a sort.
