"Magnifying Glass"
An imposing vermeil desk magnifying glass created by Luigi Valadier (1726-1785), inspired by an Etruscan mirror! Our magnifying glass, however, dates from the 19th century. It is adorned with various hardstones: lapis lazuli, jade, simbircite, onyx, carnelian and zircon beads, and an ivory handle!
