hi
hows about a copper oxide rich marble sourced from a location at a sufficien height to allow for disovable mineral inclusions, moisture, or gas as part of the initial intrusion.
as for what it is, it doesn't look like it has been regularly used as any kind of pestle for a mortar so i guess a crafted game piece is a fair bet.
