Vintage Aurora Borealis Crystal Bead Necklace with Art Deco Sterling Silver Rhinestone Clasp

This is a vintage single-strand necklace featuring graduated, faceted AB (Aurora Borealis) glass crystal beads. The beads exhibit the characteristic iridescent coating developed by Swarovski in the mid-1950s, which reflects a spectrum of colors including blue, pink, and gold. The necklace is constructed on a cord with small spacer beads between the larger faceted rounds, suggesting a mid-20th-century manufacture date, likely circa 1955-1965. A standout feature is the ornate, rectangular box clasp. The clasp is composed of sterling silver (as indicated by the provided context) and is heavily embellished with clear pavé-set rhinestones in an Art Deco-inspired geometric pattern. The central circular motif within the clasp suggests fine craftsmanship typical of high-end costume jewelry from the era. Regarding condition, the crystals appear clear with no significant chips or 'flea bites' visible, though the AB coating shows minor surface wear consistent with age. The sterling silver clasp exhibits a natural dark patina, particularly in the recessed areas of the metalwork, which is desirable as it highlights the intricate design. All rhinestones appear to be present and intact. The stringing seems secure, though it may require tension checking due to the age of the thread.
