Weight
2 - 5 grams
Description
A small, cylindrical gold-toned object featuring a clean longitudinal cut or expansion slit. The item lacks the high luster of solid gold and exhibits characteristics of high-wear plated brass or bronze. It appears to be a functional component, possibly a clasp barrel, a crimp bead for thick cord, or an industrial fastener.
Key Features
Longitudinal expansion slit, hollow cylindrical core, beveled edges at one end.
Color & Finish
Dull, antique yellow gold with a matte/satin finish; showing signs of patina, oxidation, and surface abrasion.
Hallmarks & Stamps
None visible; common for small findings or industrial parts to be unstamped or to have markings located on the interior.
Dimensions Estimate
Length: 20-25mm; Diameter: 4-6mm; Slit Width: 0.5mm.
Gemstones & Inlays
None present; functional utilitarian design.
Clasp & Closure
Internal friction-fit mechanism intended for a push-pull assembly.
Chain & Links
N/A - Solid cylindrical construction with a longitudinal expansion slit.
Craftsmanship Details
Machine-milled construction with a standard industrial cut-out; utilitarian rather than artisan quality.
Authentication Indicators
Red flags for solid gold include the uneven patina, lack of high-density luster, and 'muddy' color tone typical of gold-plated base metals. Weight appears light for the volume.
Origin & Maker
Unknown; likely mass-produced industrial or jewelry component part.
Era & Period
Modern/Late 20th Century Industrial (1970s-1990s).
Age Estimate
Circa 25-40 years old based on surface wear and alloy oxidation.
Cultural Significance
Minimal; representative of the mass-produced utility jewelry era.
Condition Notes
Fair to Poor; significant scratches, evidence of base metal peeking through (brassing), and structural dirt buildup within the channel.
Value Estimate
Negligible; value is purely functional or as scrap base metal rather than precious metal content.
Care & Maintenance
Clean with a soft damp cloth only. Avoid abrasive cleaners or ultrasonic baths which will strip the remaining gold plating.
Similar Items
Fold-over clasps, cord ends, spring-loaded barrels, and industrial pins.
Interesting Facts
Small gold-plated components like this were often used in mid-range costume jewelry of the 1980s as tension-fit clasps for leather or rubber necklaces.
