The Venetian Rosetta bead, originating from Lower Egypt, is a "chevron bead," used for barter, exchange, and trade. Also known as Issafall or Thiathiathio, it was coveted throughout Europe in 15th-century Venice by the Murano glassmakers. Three colors were used: older varieties with a green center, more recent ones with white centers, or red beads with blue and white chevrons. In Cameroon, it served as currency and a symbol of wealth, adopted by the Bamileke chiefs.
These rare beads can be found in the Museum of Alexandria in Egypt, in museums in Portugal, the Archaeological Museum of Florence in Italy, and the British Museum in London.
