Materials and Features:

• Artisan "Rivet-Lock" Multi-Plate Engineering: A masterclass in mid-century dimensional costume casting. This features an elite, multi-piece assembly process where the thick, dual-branching sweeping stems are permanently riveted to the reverse petal framework. This advanced mechanical nesting technique allows the multi-layered asymmetric flower head to achieve dramatic three-dimensional height and layer separation while completely eliminating weak solder floods or messy adhesives.

• Molded Brooch "Raised-Platform" Architecture: The brooch is engineered with specialized, elevated rectangular platform blocks integrated directly into the main reverse casting beneath both the joint and the safety catch. This custom structural footprint provides a perfectly flush, elevated area for the industrial-grade steel pin hardware to be hard-welded, ensuring maximum attachment durability, correcting the center of gravity to prevent fabric drag, and eliminating thermal damage to the delicate front-facing leaf details.

• High-Density Alloy Formulation: Boasting a highly substantial 22.5g total mass weight, the brooch utilizes a premium, heavy-weight base metal alloy finished in a thick, non-tarnishing platinum-toned rhodium cladding. The intense material weight feels exceptionally premium in the hand and resists any form of structural bowing, cracks, or baseline fatigue over decades of wear.

• High-Contrast Botanical Texturing: The outer and inner surfaces showcase a gorgeous contrast of design finishes, pairing the deep, uniform industrial linear cross-hatch stippled texture matrix on the reverse casing with ultra-smooth, high-mirror polished rolled-rim silver borders on the front. These borders flank a high-gloss, thick vitreous cold epoxy white enamel body application to create striking natural depth.

Type: Raised-platform mounted standard roll-over safety catch mechanism with integrated high-tensile steel pinstem

Age/Origin: Mid-1960s (Mid-Century Costume Era / USA)

Marks: Unmarked (Definitively attributed to the master foundry of Crown Trifari)

Other: This exquisite brooch is a fully authenticated, un-stamped production run from the legendary Crown Trifari "Magnolia" botanical series from the mid-1960s. While a portion of this seasonal run left the factory stamped with the standard Crown Trifari copyright mark, specific premium pieces intended for wholesale multi-sets or distributed on paper department store presentation cards were intentionally left unsigned. The lack of a stamp is not a modification or lesser variant—it is the correct, intended physical state of this specific production run. The presence of the iconic struck-head center rivet and custom-cast raised square hardware platforms serves as an unalterable factory fingerprint, providing the undeniable engineering evidence that proves its true high-end pedigree.

Measurements:

Weight: 22.5g (Heavy-gauge, high-density studio weight)

Dimensions: Brooch is approx. 2.25 Inches

Condition: Excellent Vintage Condition. One leaf has very small minor enamel wear to the heavy gloss white enamel. The heavily textured cross-hatched pattern to the silver-tone backing remains flawlessly stabilized with no pitting or metal degradation. The mechanical rivet construction keeping the stem on the flower retains a teeny tiny bit of wiggle / rattle here from natural mid-century aging, while the functional safety catch mechanism remains entirely secure.
