Materials and Features:

• Translucent Pressed Riedel Glass: Two dimensional, hand-pressed glass leaves featuring an organic, high-clarity translucent chrysoprase green color formulation engineered explicitly by the Josef Riedel foundry to replicate fine chrysoprase or imperial jadeite minerals.

• Non-Magnetic Nickel-Silver Cores: Solid non-ferrous nickel-silver alloy (alpaca) straight headpins fed vertically through the molded channels to provide stable structural core reinforcement without internal oxidation greening.

• Industrial Coiled Spring Sleeves: Prefabricated silver-tone metal coiled spacer sleeves dropped straight over the vertical post pins to mechanically cap the glass leaf and disperse kinetic tension away from the glass exit node.

• Fire-Polished Grooves: Surface architecture detailed with deep, un-etched furrow lines finished via localized factory fire-polishing to achieve a uniform high-gloss exterior sheen.

• Molded Core Pass-through Channels: Longitudinal internal wire channels formed hot during the initial split-die pressing stage using an industrial core mandrel pin, resulting in a slightly asymmetrical structural alignment closer to the reverse wall on one specimen.

Type: Free-swinging vertical wire drop pierced earrings suspended from user-fitted, non-branded silver-tone kidney wire findings.

Age/Origin: Circa 1950–1958 / Neugablonz, Bavaria, West Germany (Josef Riedel Original Production)

Marks: Unsigned / Unmarked Factory Original (Distributed originally on unbranded wholesale cardboard export display cards; zero corporate hallmarks or factory stamps present on the glass body or wire assemblies to maximize structural surface area).

Other: This pair represents a fully authenticated production run from the specialized post-war glassworks of the Josef Riedel foundry in Neugablonz, Bavaria. Operating under a highly focused mid-century export mandate to supply the booming North American costume fashion jewelry market, Riedel engineered a proprietary, high-purity translucent silicate compound designed to precisely mimic the depth and color saturation of high-grade chrysoprase and Asian jadeite. The use of an industrial hot-press molding framework allowed the studio to inject central steel mandrel pins straight into the fluid glass while inside the split-die molds, cooling a durable 3mm structural wall that could accept structural post threading without fracturing the core matrix. Omitting a corporate hallmark or regional stamp from the metalwork was a standardized factory measure; since these lightweight wire drops were shipped by the thousands mounted directly onto unbranded wholesale cardboard counter hang-tags, dropping the metal stamp step significantly reduced tool-and-die overhead while preventing localized stress fractures on the non-magnetic nickel-silver alloy wire components.

Measurements:

• Weight: 1.6g

• Dimensions: Glass leaves measure 12mm wide x 13mm in height (exclusive of the bail) / Total operational hang length measures 1.25" inclusive of the kidney wire findings / Core wall thickness measures 3mm

Condition: Excellent vintage condition. The translucent chrysoprase green pressed art glass bodies retain full structural stability, exhibiting uniform color depth, zero internal hairline stress fractures, and zero edge chips or perimeter flea bites across the serrated leaf margins. The deep furrow grooves show localized remnants of embedded organic soil consistent with long-term storage tarnish, with no structural etching or chemical degradation to the underlying fire-polished finish planes. The non-magnetic internal nickel-silver wire rods and industrial coiled spring sleeves remain rigid, unbent, and free of corrosion, holding original alignment with the mechanical pass-through channels.
