Arc is a very popular theme for Linux based distros. To go with it, the team has released a beautiful set of icons. Though the iconset is far from complete and covers only directories and mimetypes at the moment, it looks absolutely stunning. The missing icons are inherited from Moka by default. Is Moka is not available, Gnome icon theme as fallback. Other themes can also be inherited by editing the index.theme file.
The latest stable package can be downloaded from the releases page.
