This is a vintage 4" decorative hatpin featuring a faceted faux pearl accented by a sparkling rhinestone spacer ring.

The estimated market value for this type of vintage hatpin is between $10 and $25.

Because this piece features costume materials—specifically molded faux pearls (likely plastic or lucite) and glass rhinestones set in a non-precious base metal—it falls into the affordable collectible category. Similar vintage costume stick pins and hatpins are regularly listed and sold on platforms like eBay and Etsy within this range.
