Thisis a vintage mid-century modern enamel on copper pendant.

Handmade enameled copper jewelry was highly popular during the 1950s and 1960s, often featuring abstract, organic shapes, or freeform patterns like these chartreuse/lime green dots over a glossy black base.

The market value for an unbranded, unsigned vintage mid-century enamel on copper pendant of this style generally ranges from $15 to $30. 

Several factors influence where it falls in that range:

• Artisan vs. Unbranded: Everyday studio art pieces or unbranded hobbyist work usually sell on platforms like eBay or Etsy for $12 to $25
