Star's Pink Diamond's Sapphire. She has the same future sight ability as any other Sapphire, but Star can also summon small, blue fire stars to attack others. (I didn't classify it as a weapon, since they don't appear out of her gem.)
Star Sapphire art by me I'm not exactly sure who made the template @-_PinkDiamond_- for the original project, and for being a fantastic leader
