Materials and Features

• Anatomical V Panel Engineering: A celebrated technical configuration of the Napier workshop featuring a three-part interlocking rigid collar frame that contours perfectly around the neck, centering on a deep geometric chevron panel.

• Dual Texture Stippled Finishing: The central chevron panel showcases an intentional contrast, pairing a deeply stippled, bark-textured lower boundary with a bright, high-mirror satin-finished upper face to create multi-directional light reflection.

• Scalloped Diamond Pendant Drop: Anchors a 1.5-inch fixed diamond-shaped focal drop decorated with a central raised chevron block and an outer perimeter of twisted rope wire filigree borders.

• Solid Non Magnetic Brass Substrate: Built entirely on a premium, non-ferrous solid brass base that is completely non-magnetic throughout the body, providing a substantial weight and exceptional structural durability.

• Type: Adjustable mechanical hook clasp with a fine open-link curb chain extension tail terminating in a ribbed coin medallion weight

• Age/Origin: Circa 1964 - 1968 / USA

• Marks: Unmarked (Attributed to The Napier Company based on documented reverse framework channels, signature ribbed coin extension drops, and characteristic dual stippled panel tooling)

Measurements

• Weight: 41.0g (including findings)

• Thickness: 3mm (Thickness profile height across the main central panel)

• Dimensions: 15 inches total wearable end-to-end panel length; features a 4.5-inch extension tail; fixed pendant measures 1.5 inches in length

Condition

Good Vintage Condition. The collar necklet retains excellent structural flexibility and high eye appeal. The heavy 18k-toned gold electroplating remains bright, warm, and highly reflective across the primary stippled texturing and diamond focal drop. The reverse side exhibits an entirely clean satin face with minor, normal, age-appropriate friction scuffing and micro-thinning along the link junction points and extension hooks as expected for an authentic worn mid-century piece. All interlocking link connectors are perfectly straight and lock smoothly into the adjustable hook.
