A stone anchor or a deadweight/fixed mooring, roughly shaped as a doughnut. There are two perpendicular grooves in the central hole, attributable to the wear caused by mooring ropes.
The artefact does not present traces of biological colonisation, probably thanks to the petrographic characteristics of the stone that tends to disintegrate in tiny fragments.
