    Hello.
    I found that rock few years ago in Croatia.
    What can it be?

    May be a septarian nodule?

    Looks to be a waterworn piece of sandstone with iron staining for coloration and fractures filled with a slightly harder mineral creating the banding.

    Is this something worth keeping? Is it rare?

    its all personal preference if you want to keep the specimen. I don't know enough about the area to say anything on rarity, but it most likely is not worth much if anything to be honest
