Steven owns Rose Quartz's gem.

He is also half human, which makes him a gem hybrid.

Connie is also a full human, so she can collide with Steven's human side. That leaves his gem side/abilities to actually fuse the two together.

Steven's gem is the core of Stevonnie's being when the two fuse.

So. As long as a gem is present, they can fuse.

But on the other hand, Greg and Rose couldn't fuse. Why, you ask?

Because Rose is a full gem. She does not have a 'human side' to collide with Greg with. Either Greg has to be half gem/full gem, or Rose has to be half human.
