Vintage Purple Glass Navette Pendant Necklace

This item is a vintage-style decorative pendant necklace featuring a central, large violet or purple glass stone. The stone is faceted in an oval or teardrop shape and is securely nestled within an openwork, navette-shaped (marquise) metal frame. The frame features a scalloped lower support structure with filigree-like cutouts, while the upper shoulders of the frame are embellished with two rows of small, dark inset stones (possibly marcasite or dark crystals) that add a subtle sparkle. The metal components exhibit a yellowish-gold or brassy tone with significant signs of surface wear and oxidation, particularly at the bottom tip of the pendant where the plating appears worn away to reveal a darker base metal. The pendant is suspended by two integrated loops from a medium-gauge linked chain with flat-sided oval links. Based on the construction style and the visible wear patterns, this piece is likely mid-to-late 20th-century costume jewelry. The general craftsmanship suggests mass production rather than fine jewelry, indicated by the uneven patina and the style of the stone setting. No visible maker's marks or stamps are apparent in the image.

I have conducted a visual examination of the Vintage Purple Glass Navette Pendant Necklace. The piece is a classic example of mid-to-late 20th-century costume jewelry, characterized by a large faceted violet glass stone set within a navette-style brass-toned frame. My assessment of the condition reveals significant surface oxidation and plating loss, particularly at the lower terminal, which indicates the use of base metals rather than gold or high-quality plating. The accent stones appear to be dark glass or marcasite, common in mass-produced decorative pieces of this era. The current market for unsigned costume jewelry of this caliber is stable but heavily saturated. Comparables for similar mid-century 'unmarked' glass jewelry typically sell within the $30 to $80 range on secondary retail platforms like Etsy or eBay. The lack of a maker’s mark (such as Trifari or Miriam Haskell) and the visible wear to the finish significantly limit its collectible value. While the purple glass remains vibrant and the filigree work is aesthetically pleasing, it lacks the rarity or 'designer' provenance required to command premium pricing. Limitations: This appraisal is based solely on high-resolution imagery. Without physical inspection, I cannot verify the specific composition of the metal (acid testing) or the exact material of the accent stones. A full authentication would require an in-person examination to check for hidden hallmarks, a loupe inspection for 'flea bites' on the glass facets, and provenance documentation to determine if it was part of a specific production line. This valuation assumes the piece is non-precious base metal with molded glass.
