Weight
25-35 grams (Total weight including lenses). The actual gold content is negligible, likely under 1-2 grams of fine gold total.
Description
A classic pair of rectangular-framed spectacles featuring a minimalist yellow gold-toned bridge and matching temples. These frames represent a transitional style between the heavy plastics of the 60s and the ultra-thin metals of the 90s. The profile is sturdy yet elegant, utilizing a gold-fill process to provide the look and durability of gold without the cost and structural softness of high-karat solid metal.
Key Features
Rectangular lens geometry, slender gold-filled flat temples, and contrasting acetate tips. Double-bridge or single-bridge stability.
Color & Finish
High-polish yellow gold finish with significant oxidation/patina on the bridge and nose pad arms; temple tips are dark brown acetate.
Hallmarks & Stamps
Usually found on the inside of the bridge or temples; likely marked '1/10 12K GF' or a maker's mark like 'Shuron' or 'Bausch & Lomb'. No stamps are visible in the low-resolution photo.
Dimensions Estimate
Frame width: 135mm; Lens width: 50mm; Bridge: 20mm; Temple length: 140mm. Standard adult fit.
Gemstones & Inlays
None. Features translucent plastic nose pads and brown acetate ear sock tips.
Clasp & Closure
Standard 3-barrel or 5-barrel optical hinges at the temples with flat-head screw fasteners.
Chain & Links
N/A - Rigid frame construction with thin wire rims and flat-profile temple arms.
Craftsmanship Details
Machine-stamped components with hand-assembled hinges. The soldering at the bridge appears robust, typical of mid-tier 20th-century manufacturing.
Authentication Indicators
The 'brassy' wear at the friction points and the green verdigris are typical red flags for gold-filled or plated items rather than solid gold. Real 14K+ gold does not oxidize green.
Origin & Maker
Likely manufactured in France (based on the 'leboncoin' watermark) or the USA. Unbranded generic or 'house brand' style from a classic optical manufacturer.
Era & Period
Mid-Century Modern / 1970s Retro. Characterized by the rectangular 'navigator' or 'aviator' hybrid shape popular in professional men's eyewear.
Age Estimate
Circa 1970-1985. Based on the lens shape, hinge design, and the degradation visible on the nose pad plastics.
Cultural Significance
Iconic of the 'Professional Class' look of the late 20th century, often associated with academic, medical, or corporate fashion of the era.
Condition Notes
Fair to Good. Visible green oxidation (verdigris) on the nose pad arms and bridge, suggesting nickel/copper leaching from the base metal. Lenses appear scratched. Acetate tips show dulling.
Value Estimate
$20 - $60 USD. Value is based on vintage 'frame' appeal rather than gold melt value, which is effectively zero for most gold-filled scrap buyers.
Care & Maintenance
Gentle cleaning with a micro-fiber cloth and specialized lens cleaner. Avoid ultrasonic cleaners as they may strip old gold-filling that has been compromised by oxidation.

Interesting Facts
The 'Gold Filled' process was a standard for the eyewear industry for decades because solid gold is too soft to maintain the tension required to hold glass lenses securely.
