Type
Industrial Hardware / Raw Gold Component
Purity
Indeterminate; appears to be tarnished lower-karat gold (9K-14K) or heavily oxidized gold-plated base metal.
Gold Type
Yellow Gold (heavily patinated/tarnished)
Weight
3-5 grams based on thickness and center-void volume
Description
This item is a flat, circular metal disk with a central hole, resembling a common industrial washer. It exhibits a dull, non-reflective yellowish-brown surface characteristic of lower-karat gold that has been exposed to environmental sulfur or high-friction environments. The surface bears linear scratches and a concentric grain consistent with mechanical finishing.
Key Features
Planar circular symmetry, central aperture, weathered matte finish, and lack of decorative ornamentation.
Color & Finish
Dull, brownish-gold with significant oxidation; surface shows coarse circular machining or sanding marks.
Hallmarks & Stamps
None visible on the face; potentially located on the reverse or edge.
Dimensions Estimate
Diameter of approximately 18-22mm with a 8-10mm center hole.
Gemstones & Inlays
None; plain metal surface.
Clasp & Closure
Not applicable (flat ring/washer shape).
Chain & Links
Not applicable; flat solid construction.
Craftsmanship Details
Stamped or punched from a sheet; finished with a secondary abrasive process to flatten surfaces.
Authentication Indicators
Red flags: The dark brown coloration and lack of luster are uncommon for high-purity gold; suggests high copper/silver alloy content (low karat) or non-gold base metal. Professional XRF testing is strongly recommended to determine metal content.
Origin & Maker
Unknown; likely mass-produced industrial component or raw jewelry blank.
Era & Period
Modern Industrial/Contemporary Utility.
Age Estimate
Likely manufactured within the last 20-30 years.
Cultural Significance
Represents the utilitarian use of gold alloys in industrial or structural applications rather than decorative arts.
Condition Notes
Fair to Poor Grade. The item shows significant surface wear, oxidation, and scratches across the primary face.
Value Estimate
Negligible premium over melt value; if non-precious, the value is essentially zero.
Care & Maintenance
If solid gold, clean with a mild jewelry dip or chemical tarnish remover to restore color; if plated, avoid abrasive cleaning.

Interesting Facts
Low-karat gold (below 14K) is prone to 'tarnish' because the alloyed metals (copper and silver) react with oxygen and sulfur, whereas pure 24K gold remains chemically inert.
