Hello folks, this is a septarian sphere. It's very large. I'm selling this for Ark of Grace Orphanage in Chapata, Zambia. I wanted you to see the yellow calcite in it right there and the dark brown all-regonite and the matrix rock in it and I wanted you to see how big it is in relationship to my hand and also every side. So I thank you for looking. I will weigh it and measure it and put it in the auction. Happy bidding. Thank you for looking. Bye for now.
