I just installed Numix Icon Theme Circle on my Elementary OS Freya Beta 1. Numix Circle is my favorite icon theme beside Ieos7 icon theme. Here are some screenshots of my Elementary OS Freya desktop with Numix Circle installed.
If you like, you can use the following commands to install Numix Icon Theme Circle on Elementary OS Freya and other Ubuntu based Linux such as PinguyOS, LInuxLite, Zorin OS 9, Ubuntu 12.04, Ubuntu 14.04, Ubuntu 14.10 etc.
sudo add-apt-repository ppa:numix/ppa
sudo apt-get update
sudo apt-get install numix-icon-theme numix-icon-theme-circle numix-gtk-theme
You can then change the icon theme on Elementary OS Freya using Elementary Tweaks.
