Type
Jewelry Component (Earring Back or Cufflink Part)
Purity
Non-gold; appears to be base metal or plated steel/brass. No gold hallmarks visible.
Gold Type
Nickel or chrome plated base metal; lacks the warm undertones of white gold or rhodium-plated 18K white gold.
Weight
1.5 - 3.0 grams
Description
A functional, utilitarian metal component used as a secure backing for an earring or a toggle for a cufflink. It features a concentric circular design with a recessed center indicating a mechanical purpose rather than an ornamental one.
Key Features
Concentric ring design, threaded center, hexagonal or rounded exterior rim with visible corrosion.
Color & Finish
Cool silver-grey with visible surface pitting, oxidation, and significant plating wear near the edges exposing darker base metal.
Hallmarks & Stamps
No hallmarks, fineness stamps, or maker's marks are visible on the presented surface.
Dimensions Estimate
Diameter approximately 8mm - 10mm; petite scale.
Gemstones & Inlays
None visible; solid metal construction with concentric circular milling marks.
Clasp & Closure
Internal threading indicates a screw-back or tension-fit mechanical closure for a post.
Chain & Links
Not applicable; non-chain standalone component.
Craftsmanship Details
Machine-stamped and turned; functional but low-precision finishing with visible casting/stamping artifacts on the outer rim.
Authentication Indicators
Red flags for gold authentication: Grey/white oxidation, uneven surface texture, and lack of any purity stamps (e.g., 14K, 585). Item is likely not gold.
Origin & Maker
Likely mass-manufactured in East Asia; generic industrial quality.
Era & Period
Contemporary (late 20th century to present); utilitarian mass-produced design.
Age Estimate
Likely 5-20 years old based on wear patterns and corrosion.
Cultural Significance
Represents the mass-market accessibility of jewelry components and the shift from precious metals to affordable alloys.
Condition Notes
Poor/Fair; significant signs of oxidation (greenish/brown residue at the rim), surface scratches, and plating loss. Lacks the durability of solid gold.
Value Estimate
Negligible; metal value is minimal as it lacks precious metal content. Replacement cost for a single component is likely under $5.
Care & Maintenance
Clean with a soft dry cloth; avoid moisture as it will accelerate the visible corrosion of the base metal.

Interesting Facts
While high-end jewelry uses 14K or 18K screw-backs for security, base metal versions are common in costume jewelry to reduce costs. Gold rarely oxidizes with a dull granular texture like this.
