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. Last edited by kronckew; 29th July 2022 at 08:51 AM. |
