I like the limonite/pyrite concretion version, with or without groove.
If you follow the links at the bottom you end up at a page with a
hematite ball with two fossilized ammonites inside. All natural, too.

My money's on Mother Nature here.

The cables would have to be fairly thin to make such narrow grooves.
How do they split the matrix to find the spheres?
