Vintage Two-Row Rhinestone Tennis Bracelet

This is a classic costume jewelry tennis bracelet featuring a double-row (two-line) design. The piece is constructed with round-cut clear crystals or rhinestones, each individually set in four-prong gold-tone metal square links. The construction utilizes a flexible link system, allowing the bracelet to drape comfortably across the wrist. The closure is a fold-over clasp, which is indicative of costume jewelry styles popular from the 1960s through the late 20th century. The gold-tone finish shows signs of minor surface scratching consistent with age and previous wear. The rhinestones appear to be glass or high-grade lead crystal rather than diamonds, given the setting style and overall appearance of the metal. There is a small white price tag attached, suggesting it is currently being sold in a resale or antique environment. No visible maker's marks are present in the photo, although these are often found on the underside of the clasp. The overall craftsmanship is typical of high-quality vintage costume jewelry, showing consistent spacing and secure stone settings.

Based on my visual examination of this two-row gold-tone rhinestone tennis bracelet, I find it to be a well-preserved example of mid-to-late 20th-century costume jewelry. The construction features classic four-prong square settings with a flexible link architecture and a traditional fold-over clasp. The clear stones exhibit the high-refractive index typical of high-grade lead crystal or faceted glass, though minor abrasions consistent with age are present. The gold-tone plating shows slight oxidation near the hinges, but remains largely intact, suggesting higher-quality production standards common in the 1970s and 80s. Market demand for unmarked vintage costume jewelry remains steady but price-capped. Comparables for double-row 'line' bracelets in this style often range between $30 and $80 in retail estate settings. The lack of a visible maker’s mark (such as Trifari, Monet, or Napier) limits the ceiling for collectors. Factors positively impacting value include the secure stone settings and the functional integrity of the clasp. Limitations: This appraisal is based solely on digital images. A physical inspection is required to check for 'green' corrosion (verdigris) in the links and to perform a streak test or use a jeweler's loupe to verify the metal's base composition. Scientific testing with a thermal conductivity probe would be necessary to definitively rule out low-grade white sapphires or Moissanite, though the setting style strongly indicates non-precious materials. Provenance documentation or the discovery of a signature on the clasp’s internal tongue could potentially increase the valuation by 40-60%.
