The necklace with a massive pendant and crystals is an authentic Givenchy Paris New York creation, probably from the 1975-1990 period. The gold-plated curb chain segment and geometric, Art Deco-style pendant, the combination of a central crystal and rectangular baguette crystals set in it, are very typical of the Givenchy luxury jewelry style. The box clasp with a safety lock is typical of higher-class jewelry from the 1970-1990 period.
