This beautiful 3-piece jewelry set comes complete with matching teardrop-shaped mosaic abalone shell clipon earrings. The earrings perfectly mirror the striking geometric pattern and vibrant, iridescent blues and greens of the central necklace pendant.

The typical retail and resale value for a 25-inch bohemian/vintage abalone shell mosaic jewelry set like this generally ranges from $30 to $90, depending on where it is sold and the materials used. 

Because this set uses a non-precious backing (like resin or wood) rather than fine metals like sterling silver, its value rests primarily on its style, length, and completeness as a matching multi-piece set.

The back of the earrings reveals they are vintage clip-on earrings featuring silver-tone metal paddle-back clips.

The visible green oxidation (verdigris) around the hinges and base indicates that the hardware is made of a plated base metal (such as brass or copper) rather than fine silver. The backing material of both the pendant and earrings appears to be a lightweight molded plastic, lucite, or resin common in costume jewelry from the 1970s to 1980s.

Adjusted Valuation

Because these are clip-on costume earrings rather than pierced studs, and show some age-related wear, the realistic market value for the set is slightly more modest:

• Resale Market Value (eBay/Etsy): $25 to $45 for the complete set.

• Value Factors: Vintage collectors actively seek out bohemian abalone sets from this era, but the presence of verdigris means a buyer would need to clean the metal, slightly capping the top-end price.
