Two medium-sized lumps of pumice. The smaller one is chipped but has a less porous aspect than the larger one. The larger lump seems to have more of a beige tint whereas the other is more ochre/orange.
Pyramidal fragment of lapis lacedaemonius with a dark colour and green tints. It seems to have been worked since it has sharp angles and a few polished surfaces.
Large sandstone fragment with a beige tint and small white traces. Only one side is polished and has a curved shape (part of a vessel or other similar object)
Stone fragment of a mortar or a quern. It is rectangular and has polished surfaces (with white and dark abrasion traces) even if partly chipped. Its upper side is visibly worked and larger than its base.
