Arm-reliquary with a blessing hand, in silver adorned with precious and semi-precious stones, including two antique cameos. A commemorative inscription in Gothic characters runs around the wrist. The reliquary was donated in the year 1295 thanks to Bernarduccio Aldobrandeschi by the abbot prior of the monastery of San Giusto in Lyon to the Jesuati friars of the Florentine convent of San Giusto, who then moved to San Giovanni a Porta Romana. In 1680 it was donated by Cardinal Nerli, archbishop of Florence to the Cathedral.
