Color & Finish
High polish yellow gold finish; shows light surface scratches and minor dulling consistent with wear on plated surfaces.

Origin & Maker

Era & Period
Contemporary/Modern; Standard mass-produced jewelry style common from the late 20th century to present.
Age Estimate
Late 20th century to contemporary (circa 1980s-present) based on stamp style and link construction.
Cultural Significance
Represents the democratization of luxury, allowing consumers to achieve the aesthetic of high-carat gold at a costume jewelry price point.
Condition Notes
Good condition; the plating appears intact on the visible section without 'brassing' (the base metal showing through), though fine micro-scratches are present on the stamp tab.
Value Estimate
Resale value is minimal, typically $5 - $20 USD. It has no significant melt value because the gold content is a tiny fraction of the total weight.
Care & Maintenance
Avoid chemicals, perfumes, and water which can accelerate the wear of the gold layer. Clean only with a soft, dry cloth; do not use abrasive polish or ultrasonic cleaners which may strip the plating.
