The first floor of the museum houses works of silverware and sacred ornaments.
One of the most interesting works is the razionale, a gilded metal cape clasp that belonged to Alessandro Borgia. It is set with sixty-five coloured gems, with a clear reference to the names of the sixty-five municipalities of the Diocese of Fermo, whose names are engraved on the back.
In the same display cabinet is the Fatimid art jug with the relic of St Caesonius. This reliquary was donated to the city of Fermo by Archbishop Rinucci. Although the jug was assembled in the 17th century, the rock crystal can be dated to the year 1000.
