Hello

I inherited a chess game from my grandmother and would like to know what the pieces are made of.

The green stone feels kind of soapy if that makes any sense? The white ones feel like "normal" stone. I can scratch the white ones with the green ones. I would love to know what kind of inclusion the green ones have, but that seems like a difficult question.

Thanks in advance for the help.
