Graduated Pearl Necklace with Filigree Clasp

This item is a single-strand graduated pearl necklace, presented in a vintage-style elongated presentation box. The necklace features pearls that increase in diameter toward the center, a design typical of the early to mid-20th century. The pearls exhibit a creamy white to slightly yellowish luster, suggesting an aged patina or natural organic origin. They appear to be individually knotted on silk thread, which is a hallmark of quality craftsmanship to prevent the gems from rubbing against each other and to ensure security if the strand breaks. The strand terminates in a decorative silver-toned filigree fishhook or box clasp, which features intricate openwork detailing common in Art Deco or mid-century vintage jewelry. While no visible maker's marks are discernible from this distance, the filigree work suggests a vintage origin, likely circa 1930s-1950s. The box is a hard-shell case with a dark exterior and a padded cream-colored fabric interior, showing some staining and wear consistent with age. The pearls themselves appear to be in good vintage condition with consistent surface quality, though closer inspection for nacre wear or pitting would be required for a final valuation.
