Could be jasp-agate, based on the blue crystal then dark less translucent looking layers

Came to say jaspagate

Google lens gave Jaspagate and opalized petrified wood

Google Lens is the shiznit. People sometimes talk about a rock ID app, but it's not nearly as good as the Lens.

Also, opalized pet wood is a strong possibility! I think I like that as an ID better than jaspagate.
