This rich-looking floral brooch is composed of dark blue Celluloid and has black edging around its tips. It could almost serve as a piece of mourning jewelry. This brooch from the 1940s is in great vintage condition, though it has bowed a bit with age. The pin mechanism works well.
For those of you not familiar with Celluloid, the plastic dates back to the beginning of the 20th century to the 1930s. Celluloid is one of the earliest man-made plastics widely used in costume jewelry. Celluloid has certain characteristics that differentiate it from other plastics. In general, pieces made from Celluloid tend to be thin, light, somewhat brittle, sensitive to heat (they crack and craze), and early Celluloid can be extremely flammable (do not ever test with a hot pin!). When placed briefly in hot water, early Celluloid smells like camphor, while later cellulose acetate smells like vinegar. Celluloid jewelry should be stored carefully.
If you are a collector of vintage Celluloid jewelry, then this delightful floral brooch is right for you!
