Vintage Carved Cream Casein or Celluloid Bangle Bracelet

This is a vintage wide-width bangle bracelet, likely dating from the 1920s to the 1940s. The item is constructed from an early synthetic plastic, possibly casein (milk protein) or celluloid, featuring a creamy off-white or ivory-like color. The bracelet is characterized by a high-relief, molded or hand-carved floral motif that repeats around the entire exterior circumference. The design depicts stylized roses or carnations bordered by a finely ribbed or 'pie-crust' textured edge on both the top and bottom rims. The interior of the bangle is smooth and polished for comfort. Regarding condition, the piece shows a gentle age-related patina with minor surface grime in the crevices of the carved details, which is typical for early plastics. There are faint dark specks and a few small orange-toned spots that may suggest environmental staining or early signs of material degradation typical of celluloid 'rust'. The absence of visible mold lines suggests a higher quality of craftsmanship, potentially finished by hand after an initial molding process. The overall construction is substantial and thick, indicating a durable piece of fashion jewelry from the Art Deco or Retro eras.
