She's a start. However, right now she feels like she's written as a weapon with lore or as a mythical villain instead of as a character.

I would suggest thinking about why she does everything she does, why things that happened to her or that she witnessed shaped her the way they did. And maybe also consider what would happen if she actually tried to just shatter a Gem at the drop of a hat--something that sounds like it would be very difficult unless the Gem she's attacking is completely defenseless.
