Single-Strand Cultured Pearl Necklace with Filigree Clasp

This is a classic single-strand necklace composed of approximately 50 to 60 round cultured pearls, likely Akoya or freshwater, measuring approximately 6mm to 7mm in diameter. The pearls exhibit a creamy white body color with subtle rose overtones and a soft, satiny luster. The strand is professionally hand-knotted on white silk thread, a high-quality construction technique that ensures the pearls do not rub against one another and provides security if the strand were to break. The necklace is secured with a vintage-style decorative filigree 'fishhook' or box clasp, which appears to be crafted from sterling silver or white gold, featuring a centered seed pearl and intricate openwork metal detailing common in mid-20th-century jewelry design. The overall length suggests a 'Princess' style length, typically 17 to 19 inches. Regarding condition, the pearls appear well-matched in size and roundness with minimal visible surface pitting, though the silk string shows slight slack near the clasp, indicating it may require re-stringing due to age. There are no signs of significant nacre peeling or deep scratches. This piece is characteristic of mid-century formal jewelry, likely dating from the 1950s to 1970s, representing a timeless aesthetic of classic elegance and fine craftsmanship.
