Vintage Mother-of-Pearl Bead Necklace with Gold-Tone Clasp

This item is a vintage necklace, approximately 27 and three-quarter inches in length and weighing 91.89 grams. It features a single strand of what appear to be lustrous irregular button-shaped mother-of-pearl beads. Each bead is approximately 9 to 10 mm in size and exhibits natural variations in shape, surface texture, and iridescence, showcasing a creamy white to slightly off-white color palette with subtle overtone hues of pinkish-purple and green when light reflects. The beads are individually hand-knotted on a white string, likely silk or nylon, suggesting a measure taken to prevent all beads from scattering if the strand were to break, and also protecting the individual beads from rubbing against each other. The necklace is secured by a box clasp mechanism, which appears to be constructed from a gold-tone base metal. One side of the clasp is a simple rectangular box with a push-tab, and the other side ingeniously incorporates a larger, circular mother-of-pearl cabochon, set within a finely detailed gold-tone bezel with a pronounced rope or twisted wire decorative edge. This decorative clasp serves as both a functional closure and an additional ornamental element, hinting at a mid-20th-century aesthetic. The overall condition appears good, with a natural patina on the metal clasp consistent with age; minor wear might be present on the beads but is not readily discernible from the image. The natural variations in the mother-of-pearl indicate genuine shell material rather than imitation pearls. The craftsmanship of the knotting and the decorative clasp suggest a piece of reasonable quality from its period.

Upon examination of the provided images and details, I have assessed this vintage single-strand necklace. The piece features what appear to be genuine, irregularly shaped mother-of-pearl beads, each approximately 9-10mm. The beads exhibit a pleasing luster with subtle, desirable overtones. The overall length is substantial at 27.75 inches, and the hand-knotting between each bead indicates good quality craftsmanship, intended to protect the beads and ensure durability. The necklace's condition appears to be good for its age, consistent with a mid-20th-century origin. The primary value driver is its decorative appeal as a vintage costume piece. The gold-tone base metal clasp, while featuring an attractive mother-of-pearl cabochon and rope detailing, is not precious metal, which significantly limits the item's intrinsic value. The market for vintage mother-of-pearl necklaces of this type is relatively accessible. Comparable pieces with base metal clasps typically sell in the range of $75 to $125, depending on the platform and buyer interest. Demand is steady for well-made, classic costume jewelry. It is important to note the limitations of this appraisal, as it is based solely on images and provided information. While the beads appear to be authentic mother-of-pearl, a definitive confirmation would require physical examination. Furthermore, I cannot test the metal content of the clasp to rule out gold plating over a base metal or confirm its composition. Full authentication would involve gemological testing of the beads and metallurgical analysis of the clasp.
