Vintage Knotted Pearl Strand Necklace with Ornate Silver-Tone Box Clasp

This is a vintage single-strand necklace composed of approximately 45-50 round pearls, likely cultured or high-quality imitation glass, measuring roughly 6-7mm each. The pearls display a creamy ivory luster with subtle warm overtones. A critical feature of its construction is the hand-knotting between each bead, which prevents the pearls from rubbing against one another and ensures the necklace won't scatter if broken. The piece is secured with a vintage-style decorative box clasp, featuring a central pearl accent set within an engraved, floral-motif silver-tone metal frame. This style of clasp was highly popular from the 1940s through the 1960s. Regarding condition, the strand shows signs of significant age and wear; the silk or nylon cord has darkened and stretched significantly near the clasp, indicating it may require professional restringing. There is visible surface grime on the pearls and some oxidation/tarnish on the metal components of the clasp. No obvious maker's marks are visible in the image, but the craftsmanship of the knotting suggests a mid-century boutique production or a formal accessory of that era.
