Materials and Features:

• Premium Translucent Honey Amber Swirl Matrix: High-grade industrial cellulose acetate (Rhodoid) substrate formulated by G. Convert SA. The optical-grade material features a translucent clear to light-honey base infused with fluid, three-dimensional deep amber and rich brownish-orange swirling currents that drift beautifully beneath a high-gloss finish.

• Molded Cushion Ribbon Architecture: Expertly engineered with fluidly rounded, parallel cushion-molded ribbon ridges. The design features a heavy 6mm central thickness profile with smoothly rounded, sloped edges that optimize internal light transmission.

• Counter-Sunk Recessed Hardware Engineering: The flat interior back-facing walls feature custom mechanical counter-sink routing. The distinctive high-domed silver-tone backing plates are mounted completely flush inside these recessed round sockets, preserving clear, concentric mechanical tool traces.

• Inherent Factory Outgassing Micro-Artifacts: The flat back-facing wall preserves two microscopic, perfectly round air bubbles permanently encased and trapped entirely beneath the smooth surface layer. These internal markings occur naturally during the mid-century chemical mixing and cooling phase.

Type: Rounded cushion ribbon silhouette post earrings configured for pierced ears.

Age/Origin: Circa 1950’s / Oyonnax, France (G. Convert SA Industrial Works)

Marks: Unsigned Factory Original (Verified via the distinct 6.2g combined pair weight, characteristic lopsided geometric carving profile, and signature mechanical counter-sunk hardware assembly footprint).

Other: These earrings represent a stellar example of mid-century industrial technical polymer mastery from the historic Oyonnax valley. The pairs feature a flat back-facing profile with meticulously polished, comfort-rounded rims. The components have successfully passed comprehensive structural screening, showing a completely negative chemical reaction to Simichrome testing and producing zero phenolic or camphor odors under localized thermal testing, confirming an immaculate, non-degraded cellulose acetate structure.

Measurements:

• Weight: 6.2g (Combined pair mass; exhibits a premium hand-heft relative to scale)

• Dimensions: Approximately 1.0" x 1.0" Wide (23.2mm x 23.2mm) | Thickness: 6mm central apex with rounded sloped edges

Condition: Excellent vintage condition. The translucent light-honey base and deep amber-brownish swirling currents remain incredibly vibrant, clear, and entirely free of internal material clouding or UV-induced fading. The high-gloss exterior surface is structurally immaculate, retaining a uniform, mirror-bright buffed sheen across all ribbon ridges. The unique two-part hybrid hardware assembly features non-magnetic silver-tone posts integrated into heavily domed, magnetic base disks that are firmly and securely seated within their factory recessed grooves with zero structural shifting or loose alignment. The pair shows no wear at all and remains in immaculate condition.
