Permafusion (a portmanteau of "permanent fusion") is the name given to the act of two or more Gems spending most or all of their time fused with each other. Permafusion is often an expression of romantic or otherwise close relationships. A Gem fusion who engages in permafusion is also called such.

The term was coined by Peridot in "Too Far" to describe Garnet.
