Weight
15.0 - 25.0 grams (predominantly base metal weight)
Description
An industrial circular mounting ring featuring a thin gold-toned plating. The item consists of a flat annular face with four internal prongs or mounting tabs, one of which features a precision-drilled hole for anchoring. The luster and surface color indicate a thin electrolytic gold deposition designed for corrosion resistance rather than aesthetic luxury.
Key Features
Four internal mounting tabs, single screw hole, stamped circular geometry, and thin gold-colored surface coating
Color & Finish
Pale yellow gold color with a semi-lustrous, brushed machine finish; visible industrial tool marks
Hallmarks & Stamps
None visible; absence of purity marks suggests industrial or non-jewelry origin
Dimensions Estimate
Outer diameter: 45-55mm; inner diameter: 35-40mm; thickness: 1.5mm
Gemstones & Inlays
None; purely functional industrial design
Clasp & Closure
Bent friction tabs and a single circular mounting aperture for screw or rivet attachment
Chain & Links
N/A; flat circular ring profile with irregular interior mounting brackets
Craftsmanship Details
Mass-produced via industrial stamping and machine-punching; tabs are bent with mechanical pliers or a press brake
Authentication Indicators
Red flags for solid gold: uneven surface texture, tool marks inconsistent with fine jewelry, lack of hallmarks, and visible base metal at stress points
Origin & Maker
Unknown industrial manufacturer; likely a component for lighting, plumbing, or electronic housing
Era & Period
Contemporary Industrial (late 20th century to present)
Age Estimate
Circa 1990-present; modern stamping and machining techniques
Cultural Significance
Represents the utilitarian application of gold in modern manufacturing and engineering
Condition Notes
Fair to Poor; visible deformation on the mounting tabs, surface scratching, and potential pitting of the plating
Value Estimate
Negligible; value resides in its utility as a part, as the gold recovery cost would exceed the gold value
Care & Maintenance
Clean with a dry cloth; avoid abrasives which will easily strip the thin gold plating to reveal the base metal
