Chalcedony
Perforated, spherical beads of milky white chalcedony are worn at the present day by Italian peasant women to increase the supply of milk. Hence the Italian name for such a bead, pietra lattea. Perforated beads of white steatite, belonging to the early Iron Age, have been found near Perugia, where the chalcedony beads are worn, and it is believed that these steatite beads were borne for the same purpose.[[255]]
