Celluloid is a thermoplastic, meaning it can be moulded while hot and retains its shape once cooled. During the Great Depression of the 1920s and 30s, jewellery makers looked to new plastics like celluloid, Bakelite and Lucite to provide a more affordable alternative to precious gems. These rose beads are moulded then carved to create the intricate flower shapes.
