The main theme could be transformation. If the girl is related to stone, perhaps it's about her transformation from a stony state to something else, like becoming more human or learning to feel emotions.
One possible theme is isolation. If she is a 'stone girl', she might be isolated from others, either physically or emotionally. Maybe the story is about how she overcomes this isolation and connects with the world around her. Also, it could be about identity. She has to figure out who she is as a stone - girl, and what that means in the context of her story.

I'm not sure as I haven't read it specifically, but it could be about personal growth, family relationships, or a historical event perhaps.
The theme could also be related to discovery. The stone might be the key to a discovery in the story. It could lead the characters to uncover a hidden truth, a long - lost secret, or a new world. For example, the stone could be a special artifact that has been forgotten, and as the characters explore it, they learn about their past or their world in a new way.

Since we don't know the details of the story, it could be the stone girl herself. She might be the central figure around which the plot revolves.
Well, it might be centered around survival. If there's a creature that eats stones, it's likely in a harsh environment where normal food sources are scarce. So, the theme could be how it copes with this difficult situation and finds a way to survive against the odds. Maybe it shows the lengths a being will go to in order to stay alive.
The main theme could be revenge. In the story, the protagonist holds a long - standing grudge and plans her revenge carefully.
Well, it might be about the passage of time. The stone ship, being a solid and unchanging object, could be a symbol of how time moves on around it. It could show how things change while the ship remains, in a way highlighting the transient nature of everything else.
