A vintage gold-tone cloisonné heart-shaped stick pin featuring a red enamel background with a colorful floral bouquet design.

The market value for vintage cloisonné enamel heart stick pins typically ranges from $8 to $20.

Several factors influence the final valuation of this piece:

• Condition: Minimal chipping or cracking on the enamel and a straight pin shaft preserve the upper end of the value.

• Completeness: Having the original gold-tone safety clutch (end cap) included, as seen in the image, adds to its appeal and value.
