Next Sunday Gem icon theme will support Budgie DE.
It’s a spinoff of my Royal Z icon theme. At current state the color red (Ruby) will be available, but I’m working on a green version as well. Not sure if I get it finished to next week.
If you have icon request I should added to the icon theme, you can either write it in this thread or go to: Issues · SethStormR/Gems · GitHub
