Gold Type
Industrial Yellow Gold Plating
Weight
Estimated total weight 1-2 grams; gold content is negligible (less than 0.001 grams).
Description
A standard 3.5mm stereo audio connector featuring gold-toned plating. This item is designed for signal transmission in consumer electronics such as headphones and smartphones. While visually appealing and reflective of high-end audio standards, it is a functional industrial part rather than a piece of jewelry or bullion.
Key Features
Triple-contact TRS design (Tip, Ring, Sleeve) for stereo output and gold plating to prevent oxidation at contact points.
Color & Finish
Vibrant yellow gold color with a high-polish, functional industrial finish designed for conductivity.
Hallmarks & Stamps
None. Industrial connectors do not carry gold hallmarks as they are not precious metal items.
Dimensions Estimate
3.5mm diameter at the shaft; standard length for a headphone or auxiliary jack.
Gemstones & Inlays
None. Features black plastic/polymer insulating rings to separate the audio channels.
Clasp & Closure
Mechanical friction-fit (plug-and-socket design).
Chain & Links
Solid machined metal shaft with segmented contact points.
Craftsmanship Details
Precision machined lathe work for the shaft; electroplated finish for surface protection.
Authentication Indicators
The item is identified as non-solid gold by the absence of hallmarks, the presence of plastic insulators, and its specific industrial form.
Origin & Maker
Mass-produced electronic component, likely of East Asian manufacture (China/Taiwan) for a generic electronics brand.
Era & Period
Contemporary (Information Age/Digital Audio era).
Age Estimate
Likely manufactured within the last 5-10 years.
Cultural Significance
Represents the ubiquity of mobile audio technology in the late 20th and early 21st centuries.
Condition Notes
Fair to Poor. The connector appears to be broken off from its cable housing, with visible debris/insulation at the base. Surface shows minor scratches.
Value Estimate
Intrinsically $0.00 in gold melt value. Market value as a component is less than $1.00.
Care & Maintenance
Keep dry and clean with isopropyl alcohol if contacts become noisy; not intended for jewelry maintenance protocols.

Interesting Facts
Gold is used in electronics not for its value, but for its high conductivity and extreme resistance to corrosion compared to silver or copper.
