This is evident in episodes such as "Gem Glow" in which his love of Cookie Cat seems to activate his gem weapon. Also, further evidence in "Bubble Buddies" points to this fact because he summons a magic bubble to protect his love interest, Connie. Coincidence?

Please post your own opinion.

I assumed it was activated by love as well as a part of Rose may still be in the gem protecting Steven when she can/needs to. I believe in "Rose's Room" Rose hears Steven wanting to be alone and opens her room to give him what he wants as well as to probably teach him a lesson. That's only my opinion though.
