Weathered Brass or Lower-Purity Gold-Plated Scrap Fragment
Raw Gold / Industrial Scrap · Yellow Gold plating or Brass alloy (copper/zinc mixture)
Purity: Likely non-precious or gold-plated; no visible hallmarks or high-karat indicators
Type
Raw Gold / Industrial Scrap
Purity
Likely non-precious or gold-plated; no visible hallmarks or high-karat indicators
Gold Type
Yellow Gold plating or Brass alloy (copper/zinc mixture)
Weight
0.1 to 0.5 grams
Description
A small, rectangular metal fragment displaying a yellowish hue heavily obscured by oxidation. The piece shows distinct green spotting (verdigris) and a darkened, nearly black edge, suggesting high copper content rather than solid gold.
Key Features
Sharp machine-cut edges, flat uniform thickness, and prominent green corrosion spots typical of base metal alloys.
Color & Finish
Dull yellow with significant green verdigris oxidation and dark tarnish
Hallmarks & Stamps
None visible; absence of stamps suggests non-jewelry industrial origins or base metal
Dimensions Estimate
Approximately 5mm x 5mm x 0.5mm
Gemstones & Inlays
None
Clasp & Closure
Not applicable; raw fragment
Chain & Links
Not applicable; flat rectangular profile
Craftsmanship Details
Basic industrial shearing; no artistic finishing, polishing, or artisanal detail.
Authentication Indicators
Red flags: Presence of green oxidation (verdigris) and uneven dark tarnish; these are primary indicators of base metals like brass or copper rather than solid gold.
Origin & Maker
Unknown; likely industrial component or discarded costume jewelry fragment
Era & Period
Modern / Industrial age
Age Estimate
Recent; 20th to 21st century based on machine-cut edges
Cultural Significance
Utility scrap; representative of the mass production of gold-colored alloys for industrial or low-cost fashion use.
Condition Notes
Poor; heavily oxidized with verdigris and significant surface tarnish, indicating chemical reaction incompatible with high-purity gold.
Value Estimate
Negligible; likely melt value of base metal copper/brass (~$0.01) unless proven to be gold-filled.
Care & Maintenance
Requires cleaning with mild acetic acid or specialized brass cleaner, though value is negligible.
Similar Items
Gold-filled scrap, brass plate, or gold-plated electronic connectors.
Interesting Facts
Real gold does not oxidize to green; that reaction is unique to copper reacting with moisture or acids to form copper carbonates.
