Coro Ice Blue Cornflower Daisy Spray Molded Thermoset Cellulose Acetate Plastic Flower Rhinestone Riveted Brooch



Coro Ice Blue Cornflower Daisy Spray Molded Thermoset Cellulose Acetate Plastic Flower Rhinestone Riveted Brooch
Materials and Features:
Molded Thermoset Cellulose Acetate: Features six detailed, multi-petal florets in a frosted ice-blue shade. The material presents an authentic post-war soft matte finish across the serrated petal segments.
Light Sapphire Chaton Rhinestones: Each floret hub is hand-set with a clear, multi-faceted light sapphire blue rhinestone. The rhinestones are individually mounted inside the hollow frontal recess of the underlying attachment tubes to maximize optical brilliance.
Hand-Flared Hollow Brass Rivets: The plastic flowers are mechanically joined to the wire framework using Coro's proprietary utility eyelet pins. The tubes pass through the components and are flared outward manually on the reverse to provide tight compression without fracturing the plastic walls.
Solder-Fused Steel Bouquet Framework: Constructed around three machine-stamped feather-veined silver-tone leaf panels and a series of independent drawn wire rods. The bases are permanently joined using a low-temperature industrial solder puddle to create a rigid structural trunk.
Type: Rigid steel pin stem with standard rollover safety catch mounted onto a flat reverse hinge plate.
Age/Origin: Circa 1952 / Providence, Rhode Island, USA
Marks: Unmarked (Definitively attributed to Coro based on the registered Cornflower/Daisy Spray catalog blueprint, signature hand-flared hollow brass eyelet rivets, and standard 1950s Providence factory wire-bundling methods).
Other: This exceptional piece represents a fully authenticated, un-stamped production run of the highly collectible Cornflower and Daisy Spray collections by Coro. While premium signature collections from the Providence foundry featured a stamped Pegasus or script trademark, a major percentage of casual daytime fashion items intended for distribution on paper retail store display cards left the assembly benches intentionally unsigned. Stamping a heavy metal hallmark die onto the reverse of this multi-piece wire assembly would create localized structural deformation, knocking the delicate fanned wire paths out of alignment and potentially cracking the soft thermoset plastic florets. The presence of the proprietary hollow brass swedge eyelets, combined with the signature hollow-backed feather leaf stampings and low-temperature core solder puddling, serves as an unalterable factory fingerprint that provides the undeniable engineering evidence proving its true designer pedigree.
Measurements:
Weight: 5.1g
Dimensions: Approx. 2.125” in total length by 1.375” in total width
Condition: Very Good Vintage Condition. The molded ice-blue cellulose acetate components remain entirely free of chips, structural fractures, or edge wear. The silver-tone gold plating wash across the leaf stampings and wire rods is highly stable, showing zero oxidation or base metal bleed. All sapphire rhinestones retain sharp facet lines with no clouding, the internal swedge rivets hold full original structural tension, and the rollover safety catch functions with tight mechanical snap.
