Sterling silver pendant necklace with cushion-cut black onyx stone, marked 'PLATA 925'

This pendant represents Mexican silver jewelry craftsmanship, likely produced in the mid to late 20th century when Taxco and other Mexican silver centers flourished. The 'PLATA 925' marking (Spanish for 'silver 925') confirms this is genuine sterling silver, a hallmark of Mexican silver jewelry production. Mexican artisans have been renowned for their silverwork since the 1930s, when William Spratling revitalized the craft in Taxco, creating a thriving industry that combined traditional techniques with modernist design aesthetics. Sterling silver and onyx jewelry from Mexico appeals to collectors of Latin American decorative arts, vintage jewelry enthusiasts, and those who appreciate handcrafted artisan work. These pieces are valued for their quality craftsmanship, cultural significance, and the enduring popularity of Mexican silver jewelry in the international market. The combination of sterling silver with black onyx creates a striking contrast that has remained fashionable across decades, making these pieces both collectible and wearable.
