This is a vintage heart-shaped cloisonné floral stick pin with a dark enamel background and gold-tone trim. 

The back of the stick pin features a gold-tone, textured surface with an attached, curved pin shank.

The textured backing and the way the metal stem is hooked and soldered directly onto the heart are highly characteristic of traditional cloisonné, champlevé, or painted enamel jewelry from the mid-to-late 20th century. The texture helps the enamel adhere to the metal on the front during the firing process and prevents the piece from warping.

The estimated retail value of this vintage heart-shaped cloisonné floral stick pin is typically between $10 and $25.

Because these pieces were widely produced as affordable costume fashion jewelry during the 1970s and 1980s, their market value depends entirely on condition: 

• $10 – $15: Average secondary market value on platforms like eBay if the pin is unsigned or shows minor surface wear.

• $18 – $25: Retail price on vintage curated storefronts like Etsy when the enamel is entirely free of chips, cracks, or heavy pitting, and it includes the matching metal end-cap (clasp)
