Well, could be but I don't think so, because iron is magnetic this stone is not..

You both are on the same track. Ironstone (iron oxides). Iron oxides do not have to be magnetic. Hematite(Iron oxide with red streak) is only magnetic after heating. Looks like the stuff found in Utah with the sandstone inner core- Also Mars- Here is an interesting link about Utah/Mars hematite concretions. Look at the photos.

Cool, they look almost like my stone. I looked up on google on "Shaman stones" as they also are called.
The biggest difference is the (possible) iron concentration on mine.
