Joseph Mallard

Here is another marble that I was curious about and want to know if I am way off. Could it be a MFC Opaque Tourqoize? And if not how does one differentiate who it might be if it's not them.

Thank you sir, that helps me understand and I still think it's a good looking marble. Much appreciated.

Hello folks, I'm usually hesitant to post because of my lack of knowledge. However, I know the only real way to find out is they ask the experts. I have been working hard at learning marbles for 6 months, I know now it will take years but it's so much fun. Is this a Christian agate striped opaque?
