Thunderegg with Agate Inclusion

This is a small thunderegg with fortification agate growing inside of it that I cut open to tumble polish. The agate took a polish, the porous surrounding material did not.

Beautiful. Rocks are so fascinating.

I remember seeing these for the first time as a child and I was astounded by the concept and I always remember that when I see them even now
