Welcome to the forum, 'collector. Are you sure that ball has a 12 inches diameter. Maybe you mean perimeter ?
My stone balls have circa 7 1/2 inches diameter and no way i could fit them inside the palm of my hand .
... Or am i missing something ? .

Could it also be a catapult projectile as well as a cannonball? The use of mechanical artillery and cannons did overlap for awhile in the late Middle Ages. Or the sphere could be a lot older than that and possibly date from Byzantine or Roman times...

What is its backstory? Where did you get it, what were you told about it by the vendor, where are you now? Can you tell what kind of rock it is made from? Provenance is everything.



C=πD (or 2πr), Pi (π) =3.141592654... so



13=3.14159 D
D=13/3,14159=4.138 inches.


I can buy stone spheres made as modern decorative garden ornaments in various sizes. Caveat Emptor.

Catapult projectiles are much less dressed, they show lots of dimples and bumps, as they don't have to go through a barrel.
