This is a cut and polished Septarian nodule from Morocco, how cool!

It contains a beautiful and unique inner structure. Septarian is a form of sedimentary geode that formed on sea beds millions of years ago. When these "mud balls" dried out they cracked and formed hollow interiors. The interiors usually become either partly or completely full with other minerals, such as calcite, giving septarian its unusual texture and features. Calcite was carried down into the cracks of the mud balls where it formed.
