Vintage White Nephrite Jade or Milk Glass Beaded Necklace with Filigree Clasp

This item is a single-strand beaded necklace featuring uniform, spherical white beads. The beads possess a soft, waxy luster and a translucent to opaque milky-white appearance, characteristic of white nephrite jade or high-quality milk glass. Each bead is individually hand-knotted on a white cord, an indicator of traditional craftsmanship intended to protect the beads from friction and ensure the strand's integrity if broken. The necklace is secured with a vintage-style silver-toned metal fishhook clasp, featuring decorative openwork filigree in an oval shape. This type of clasp was particularly popular from the mid-20th century, roughly the 1940s through the 1960s. Regarding condition, the beads appear mostly smooth; however, one bead near the bottom curve shows a distinct purple mark or surface blemish, possibly ink or a manufacturing flaw. There is visible surface grime on both the beads and the string, likely due to handling or age. No obvious cracks or chips are visible on the bead surfaces from this perspective, and the knotting remains tight, suggesting the structural condition is well-preserved despite needing a careful cleaning. The overall aesthetic is one of classic mid-century elegance, often referred to as 'mutton fat' jade in Asian jewelry contexts.

This appraisal concerns a single-strand vintage necklace featuring uniform, milky-white spherical beads with a silver-tone filigree fishhook clasp. Based on my visual examination, the beads exhibit the soft, waxy luster typical of either 'mutton fat' nephrite jade or high-quality vintage milk glass (Peking glass). The individual hand-knotting is a positive indicator of quality construction common to the mid-20th century (circa 1940s-1960s). However, determining the specific material is the critical variable here completely altering the valuation. If these are authentic nephrite jade, the value falls on the higher end ($150-$250+), whereas milk glass places it in the costume jewelry category ($40-$80). The visible purple surface mark on one bead is a concern; if this is a surface stain, it likely diminishes value slightly, but if it is an inclusion within the stone, it points more strongly toward natural jade. The clasp is base metal rather than sterling silver, which favors the costume jewelry attribution. Currently, the market for mid-century beaded jewelry is stable, but genuine jade commands significantly higher premiums due to demand in Asian markets. Without physical testing—specifically checking the stone's temperature (cold to the touch), Mohs hardness, and specific gravity—I cannot definitively rule out glass. Therefore, this valuation provides a conservative range covering strictly collectible vintage costume jewelry up to entry-level estate jade pieces. A full authentication would require gemological testing to confirm the material composition.
