''To chase away illusions and all sorts of vain imaginations, let us take the Chalcedony stone, which is pale and dark; if you pierce it in the middle and hang it around your neck with another stone called Serenibus, you will not fear fantastic illusions. By its virtue, one overcomes all one's enemies, and it preserves the body in strength and vigour.''
''Chalcedony in France is very present. Among the most beautiful deposits we will mention the Etelon and Châtelperron in Allier. Very beautiful bluish guttular chalcedonies were also harvested in the past in the asphalt mines of the region of Clermont-Ferrand, Puy-de-Dôme. Also noteworthy is Aquitaine for its large hilly specimens and the Massif de l'Estérel in the South of France, well known for its nodules of agate and quartz.''
