Craftsmanship Details
Machine-stamped or die-struck. The edges show signs of finishing, but surface imperfections suggest a budget-friendly production method rather than artisanal hand-fabrication.

Cultural Significance
Represents the trend of 'accessible luxury' where gold-tone accessories allowed wider social classes to adopt gold-centered fashion aesthetics.
Condition Notes
Fair to Good. Visible surface wear including scratches and pitting (porosity). Some darkening suggests the protective plating is thinning or reacting to the environment.
Value Estimate
$5.00 - $20.00. Value is primarily aesthetic/decorative. Melt value is negligible as the item is not solid gold.
Care & Maintenance
Keep away from moisture and perfume to prevent further plating erosion. Clean only with a dry, soft microfiber cloth. Do not use chemical cleaners.
