Materials and Features:

• Premium Translucent Rhodoid Matrix: High-grade industrial cellulose acetate compound formulated with an optical-grade translucent cherry wine base. The specialized polymer offers an ultra-light material-to-volume mass ratio that delivers an authentic, musical glass-marble acoustic "clank" when stacked or moved.

• Variable-Density Pearlescent Swirling: Suspension-blended with a floating, multi-layered milky white pearlescent swirling agent. The marbled filaments are distributed organically throughout the thick cross-section, creating three-dimensional visual depth that shifts and reflects light through the translucent substrate.

• Graduated Convex Dome Geometry: Engineered with an advanced mid-century mold profile featuring sharp 2mm comfort-rounded outer rims that graduate cleanly into a prominent 5mm central dome apex. This architectural taper maximizes the structural refraction of the marbled pattern while remaining highly ergonomic on the wrist.

• Hand-Finished High-Sheen Surface: The entire exterior face has been hand-buffed and polished using fine vintage workshop abrasives, resulting in a glass-smooth, mirror-bright reflective sheen that amplifies the deep wine-red colorway without the use of artificial topical varnishes.

Type: Continuous solid-loop cylindrical fashion bangle bracelet designed to slip over the hand.

Age/Origin: Circa 1950’s / Oyonnax, France (Rhône-Alpes Plastics Basin)

Marks: Attributed Tier (Unsigned historical production; verified via the distinct 35.4g material density metric, characteristic 1.25-inch wide domed template, and signature two-part mechanical injection mold assembly footprint).

Other: This exceptional specimen represents a premium example of post-war European technical mastery within the historic Oyonnax plastics cluster. To replicate luxury organic materials like carved agate and poured glass, French artisans utilized specialized injection molding tooling that left behind structural fingerprints. The piece features a distinct dual-point factory seam layout: an superficial outer surface trace line on one side, paired with a deep through-fuse line and outer side-wall offset exactly 180 degrees across from it on the reverse wall. These features represent a forensic signature of a two-part industrial injection die cavity. The bracelet has successfully passed strict structural screening, showing a negative reaction to Simichrome chemical testing and producing zero phenolic or camphor odors under localized thermal testing, confirming an immaculate, non-degraded cellulose acetate structure.

Measurements:

• Weight: 35.4g (Exhibits the classic lightweight density characteristic of authentic vintage European Rhodoid)

• Dimensions: Width: 1.25" Wide (31.75mm) | Cross-Sectional Thickness: 5mm Center graduating sharply to 2mm Edges | Internal Diameter: Standard vintage fit

Condition: Excellent vintage condition. The translucent cherry-wine body and milky white pearlescent swirls remain exceptionally vibrant, crisp, and completely free of internal material clouding or UV-induced yellowing. The high-gloss exterior surface is structurally immaculate, displaying only faint micro-scratches consistent with gentle, archival storage and age. The interior wall is completely smooth, lacking any deep gouges, material loss, or stress fracture lines. The dual injection-molding factory seams remain entirely stable, rigid, and factory-tight with zero signs of structural separation or chemical warping.
