Materials and Features

• Atomic Cross-Hatched Honeycomb Link Engineering: A flexible mid-century modular sequence featuring custom-punched geometric openwork cluster connector plaques finished on both the front and reverse sides with precise, microscopic knurled cross-hatch stippling.

• Diamond Cut Faceted Pigmentation: Accented by alternating heavy-gauge elongated oval links featuring crisp, multi-angled mechanical diamond-cut edge facets that slice through light to generate a brilliant, shimmering golden reflection.

• High Purity Electroplated Finish: Coated via a heavy mid-century electroplating process utilizing a high-purity 22k–24k gold solution; this specific historical alloy standard embeds real elemental gold directly into the surface pores, yielding an exceptionally bright, rich, deep champagne warmth that fundamentally resists tarnishing, flaking, and atmospheric aging over decades.

• Heavy Gauge Luxury Base DNA: Formed entirely from a substantial, high-density non-magnetic jewelers brass alloy core base that provides a premium weight and exceptional structural durability across the 33.5-inch drape.

• Type: Adjustable mechanical hook clasp with fine curb extension chain

• Age/Origin: Circa 1958 - 1966 / Hong Kong

• Marks: HONG KONG (Crisply stamped on the flat face of the hook fastener)

Measurements

• Weight: 38.0g (including findings)

• Thickness: 2mm (Wire gauge profile thickness)

• Dimensions: 33.5 inches total end-to-end wearable length; individual main loops scale to 1.125 inches widest point

Condition

Excellent Archival Condition. The necklace displays magnificent structural flexibility and an immaculate, heavy metallic finish. The complex cross-hatched and diamond-cut textured surfaces are perfectly crisp, showing zero wear to the facet peaks, localized gold plate loss, or underlying base exposure. Every interlocking loop and stamped openwork cluster block remains completely straight with no distortion or tool scars. The mechanical hook fastener and expansion link tail operate perfectly with reliable closure tension.
